Cool hack! Along the same (disturbed) lines, I wonder if it would be possible to do tcp/ip over SMS using a tun or tap type driver? i.e. take the packet, encode, break into parts, SMS to a remote gateway, undo the packing, reassemble and send it on it's way. Sort of like RFC 1149, "A Standard for the Transmission of IP Datagrams on Avian Carriers" but using SMS. Probably slower than pigeons though :-)
