For this sort of application (tunneling), PPPoE is a win in most ways.
It's got low overhead, isn't hard to administer, is reasonably secure,
and doesn't require awkward architectural decisions (e.g. superimposing
a subnet with reserved addresses upon your current LAN to do PPP over
UDP or TCP).

I just wish it would work! I may be able to help hunt down the problem 
myself, but need to get the link up first. THEN I can roll up my 
sleeves and start analyzing C code. (I don't much like C, but I can 
use it if I have to.)
