Sorry, I misunderstood. We're saying the same thing.

Sorry, I misunderstood again. I mean user-ppp :OI

I believe it's completely independent although the VJ header
compression code is derived from the same thing (the rfc AFAIK). All
the stuff I've done since '96/'97 is original.
If anyone's been in the pppd kernel code they'd know why... it's
``evolved'' and has a lot of nasty bits that should really be
re-designed away (IMHO).
