These are different to the normal XBee modules because they are surface mount and additionally can interface to a host using SPI as well as serial. The backpack also features 3 LEDs for status signals as well as two FTDI headers (one for the RPi and one for the XBee), as well as being able to host a 'normal' XBee module (though of course you can't use SPI with those).

Hardware & Peripherals:
Hardware - detailed information about the Raspberry Pi boards.
Hardware History - guide to the Raspberry Pi models.
Low-level Peripherals - using the GPIO and other connectors.
Expansion Boards - GPIO plug-in boards providing additional functionality.
Screens - attaching a screen to the Raspberry Pi.
Cases - lots of nice cases to protect the Raspberry Pi.
Other Peripherals - all sorts of peripherals used with the Raspberry Pi.
On the Raspberry Pi, there are several connections which can be used for expansion:
- The Rpi GPIO (General Purpose Input/Output) pins are exposed, that means that expansion boards are able to talk directly to the CPU.
- The DSI connector will allow low-level interfacing with LCDs and other displays.
- The CSI connector will allow camera modules to be added in future.
Current expansion boards
- main page: RPi Gertboard
This board is a buffer between your Rpi and the real world, use it to flash LEDs on and off, drive motors, run sensors and all that other fun stuff.
BitWizard has a Raspberrypi serial breakout board. It breaks out four serial buses from the GPIO port.
BitWizard then has a series SPI (or I2C) expansion boards that can be daisy-chained off the SPI (or I2C) buses of the expansion board. A virtually unlimited number of expansion boards can be connected. Expansion boards are available that drive a simple 16x2 text LCD, more general purpose IOs, servos, temperature sensors, relays, optocouplers etc.
On 2nd January 2012, CJE/4D announced that they have a real-time clock (RTC) expansion board in the works: 
Pi-Wire Homelabs are developing options for connection of a 1-wire bus to the RaspberryPi. Boards include SPI breakout connections for future boards.
Slice of Pi
Slice of Pi Ciseco have produced a convienient small break out board for the Raspberry PI. XBee style connector for XRF / XBee / RN-XV / XBT / RF-BEE etc. Has the SPI and I2C pins on one standard 8 way header and the Raspberry PI's 8 general purpose I/O pins on another for easy access. Comes as a kit of parts that needs to be soldered. Construction is very easy and suitable for children with basic soldering skills.
GPIO isolated expansion/RTC
UT Electronics is developing a expansion board containing a fully isolated 16-I/O I2C GPIO expander and RTC, with extensive options for further expansion. C and Python libraries will be available at launch. The board will probably be sold as a kit, with SMT components already in place.

Arduino Shield and Raspberry Pi
a little board with Arduino socket and Raspberry Pi socket you can power the boards with 12Volt or 5Volt http://www.progetti-hw-sw.it/raspberry.htm
Relay board and Raspberry Pi GPIO
a board with 8 relays and 8 input with a Raspberry Pi socket you can power the boards with 12Volt, the board has a DIN rail container http://www.progetti-hw-sw.it/raspberry.htm
RPi UserPort is a digital and analogue I/O board for the Raspberry Pi. UserPort replicates the original BBC Micros digital User Port and Analogue Port but uses more modern components such as the MCP23S17 16-ch GPIO and MCP3204 4-ch 12-bit ADC.
RPi MIDI Breakout Board
RPi MIDI Breakout Board is a simple MIDI breakout board for the Raspberry Pi using the hardware UART from the RPi's expansion interface
RPi RS232 Breakout Board
RPi RS232 Breakout Board is a simple RS232 breakout board for the Raspberry Pi
Quick2Wire GPIO Expansion Board
Quick2Wire GPIO board and experimenters kit is an extension board for the Raspberry Pi that has level converters to allow the driving of TTL and real world devices such as LED's and switches. It will also provide an experimenters kit, a software framework and a number of tutorials.
Raspberry Pi IO Interface
forum thread showing 'paper mockup'. Another buffered IO expander.
PONTE initial post An arduino shield bridge from Omer and SKPang
“À la mode” is an Arduino clone specifically designed to interface with the Raspberry Pi. You can of course connect a standard Arduino to a Pi USB port using a cord, but when you want a turnkey solution, how about an Arduino compatible “plate” (shield) that fits right on top of the Raspberry Pi with direct access to GPIO port? The Linux side handles all of the displays, human interfaces, and number crunching. The low power Arduino compatible “à la mode” board handles sensors, servos/motors, and provides a highly accurate real time clock.
XBee ZB SMT Backpack
The Raspberry Pi XBee ZB SMT Backpack by bootc is a carrier board for Digi XBee ZB SMT modules. These are different to the normal XBee modules because they are surface mount and additionally can interface to a host using SPI as well as serial. The backpack also features 3 LEDs for status signals as well as two FTDI headers (one for the RPi and one for the XBee), as well as being able to host a 'normal' XBee module (though of course you can't use SPI with those).
