The FreeBSD implementation uses netgraph, and though there has been some
talk about porting it to NetBSD, it hasn't been done yet. Netgraph is
definitely the way to go IMHO. It's basically networking lego implemented
in kernel space. It would make it far easier to implement 802.1Q VLANs
(though I believe this has now been done in NetBSD-current), MPLS, etc..

I'll gladly help out with a netgraph implementation. Kernel level
PPPoE will come along for free, since you could take it straight out
of FreeBSD with minimal porting once netgraph itself has been done.
