It has been pointed out that the "adaptors" that normally come with the smaller MMC-like flash cards (RS-MMC, mini-SD, micro-SD, etc) make reasonable (if somewhat large) sockets for the small flash cards.

These mostly use the sockets available on eBay from eBay Seller exdwh, and are designed to be reasonably manufacturable using hobbyist PCB fabrication techniques.
