To be frank modem DSP is the relatively easy part. The more difficult part is the implementation and testing of all those standards; speed negotiation, error checking, recovery, compression etc. Getting the DSP to equalize the channel especially if you don't have much a processing power concern is not that difficult. It is not , IMNSHO, usefull at all to have a modem which is not a "modem". Very few people would have any use for something which doesn't talk to the Internet, IOW, an ISP.

Gzzz. DSP is the hard part. You could use gzip for compression if you really wanted to, and error correction is usually done with crc + retransmits, so that's not problem, either.
Well, you could end up with driver that would only be able to connect linux-to-linux, but I guess that it is WAY better than no driver at all.
