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.
