It *may* still be broken.  The rfc is lousy at explaining how it's 
supposed to work at negotiation time.

The *real* problem is ppp's LQM "policy" - something that's left to 
the discression of the implementation.....  I need to talk to some 
third-party ppp implementation to discover what the concensus is.  
The sources of pppd have as many ????s as I have.  Unfortunately, 
linux uses pppd too, so I won't get much mileage from talking to 
that, and the NT RAS won't talk to my null-modem cable (the breakout 
box says it's putting up the correct lines, but the RAS never sees 
anything, and the client sends stuff and never gets a reply) !!!!

Mutter mutter mutter.
