I'm running v0.8.7 already.

I would be inclined to use nodetach.  I haven't really delved into your
code, but there's another guy out there who has some info on a
non-standards-based VPN that runs pppd over an ssh connection.  He uses a
home-grown program called pty-redir to grab both ends of a
pseudo-terminal, and you guys might find that code useful, or not.  Also,
it doesn't work at all under (at least) Solaris, due to some differences
in pty implementation.

Also, I'm sure you're aware that pppd writes its pid in /var/run/ppp?.pid
under linux, and that you can't figure a clean way to grab the right one,
but, then again, maybe that was the one piece of informtaion you needed.

_Been_ opensource.  If I had more time, I'd be helping more than just
submitting bug reports.

And nothing about NT not working properly surprises me.
