I was thinking along the same lines, but a little investigation revealed that:

1.  My ISP is using PPP, but not PAP.  That's makes a PIC dialup a little
easier.
2.  My ISP doesn't support TFTP.

Off hand, I'd guess that UDP might be doable on a PIC.  But I can't think
of any common UDP services that would be useful for transfering a moderate
amount of data.

Anyone got a workable idea?
