NAT and PPTP

[Brett Glass]

By the way, one thing that MIGHT work instead of PoPToP is to
create something like FreeBSD's pppoed for pptp. It'd connect
the Netgraph PPTP implementation to userland PPP, in much the
same way that pppoed connects the Netgraph PPPoE implementation
to userland PPP.

I'll bet that Brian Somers could crank this out in a hurry, since
he was the author of pppoed. Maybe we should commission it.
