Ack. Perhaps I should have been more precise with my terminology. :)

What I'm doing is using OpenSSH as a conduit, such that on both the
client and server machines, pppd is run through the tty that ssh can
create with the -t option. The result is that on the client side, pppd
sends PPP data through the SSH connection to the other side, where the
server is ALSO running pppd. They then exchange binary PPP information
through the ssh tty.

Server		OpenSSH		Client
------		-------		------
pppd->		->tty<-		<-pppd
