I've crated an initial Wiki page about the possible / intended modifications from a classic phoned design at http://bb.osmocom.org/trac/wiki/Custom_Calypso_Board :

• board-edge connector for plugging many boards into one backplane

Feel free to discuss other extensions/modifications you may have in mind.

How about USB to the backplane if 12Mbps is enough throughput? The contacts are specified on the MiniPCI-E edge connector. Could also try some trick with the SIM signals for when using real SIM.
