Automatic networking via CDMA/etc.

Dapper drake's automatic network switching to go between wired and wireless networks is an excellent start. It would be good to take this to the next level by adding support for detection and use of CDMA cards, like the Verizon Wireless Broadband service. Several of these cards work with Linux just fine. Suggestion: automatically use the best card available: wired, else wifi, else CDMA.
