You'd have to implement TCP/IP in userspace also, which wouldn't be too nice.
With recent kernels (2.6.29 and up), you'd rather want to create a new network
kernel namespace, containing the MMS interface and the one or few processes
sending or receiving MMS.
That avoids the IP range conflicts while not needing to reimplement TCP/IP. It
also still works if the modem exposes GPRS through sone kernel driver such
that you cannot cleanly send and receive IP packets in userspace anyway.
Currently, there aren't any in oFono, as both PPP and Phonet can provide IP
packets to userspace. But that does not mean there won't ever be any.
