I guess in a perfect world, Linux would provide a common control interface
for GPRS as it already does WiFi (and maybe soon will for WiMAX?). But I am
not sure we can unify AT+PPP, Phonet, AT+Ethernet and who knows what else,
behind a common Netlink interface, especially as AT commands have always
been done in userland anyway.

The AT stuff is really problematic. Look at the hoops ISDN and software
modem drivers go through to emulate AT commands. I know even of a CDC-ACM
modem which can't deal with AT commands inline (that's within spec).
It seems to me we should have a modem API in kernel.
