Yes, perfectly so. lwIP is a very complete TCP/IP (v4) stack.

For starters, download a recent version either from CVS or as an 
archive, as well as the "contrib" module.

The contrib module contains many working glue code to use lwIP in 
different real-world platforms (compilers, network drivers, processors,
with or without operating system support).

Also, your might want to browse through the mailing list archives.

There has at least been one company on the list using lwIP with GPRS
with success.

Regards,

Leon.
