pppd doesn't necessarily run over a modem; you can "tunnel" it over another IP connection.
I have in fact done this very thing. Use ssh to (encrypted) log in to the ppp server, and start pppd at each end. It's been a while; I think I had to tweak something to make it work over a pty instead of a serial port.

You need to use my ssh tunneling patch: ftp://suburbia.net/pub/mailinglists/best-of-security/179 -- "Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies, The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for own good will torment us without end, for they do so with the approval of their own conscience." - C.S.
