unnumbered PPPoE

[Talmage]

I've been reading through manpages and tutorials but have not been  
able to get an answer to a question I have.

I am wondering if it's possible to use OpenBSD as an unnumbered PPPoE  
client bridge.  Basically a transparent bridge that processes packets  
for PPPoE so the rest of the network doesn't have to deal with PPPoE.
