Interesting. BTW, i would recommends to use any recent 3G modem instead 
of Arduino gsm shield. Some pros and cons:

 1. Cheaper (you can find one for something like 5-15USD on local auctions)
 2. Supports recent data (HDSPA+, etc.) connectivity as well as SMS and
    Voice
 3. Voice functionality already integrated with Asterisk (chan_dongle),
    so easy to integrate with any VoIP software and hardware
 4. Can be unplugged any time and used as 3G dongle if needed :)

I am using this configuration (raspberry + chan_dongle + modem) as 
outgoing gateway to the mobile network. If i need this dongle as backup 
ISP connection i am just unplugging it and all traffic goes via backup 
SIP link :)
