I have run into this problem before, and I'm wondering how difficult
it would be to get my PC to emulate a TDD - I'm guessing that it's 
trivial but would require hardware - I'm supposing that it wouldn't
be possible to convince my modem to talk to the things.

Probably easier to send a PC and modem to my deaf relative...
