The FreeBSD ppp implementation is all in user-land.  is there a good
techinical reason why this couldn't be ported to NetBSD and used as
the standard PPP on NetBSD.  I used it for a couple of months when
I was running FreeBSD at home and it worked fairly well for me (although
I have a fairly low traffic link, so maybe there are performance 
problems that I am not aware of).

It worked with the tun driver.

The release notes for it said that it had been ported to NetBSD in 
earlier versions, but that the author had lost access to NetBSD 
machines and that it only worked on FreeBSD at this point (or something
to that effect).
