First, are there any patent issues that you are aware of?

The fundamental problem is that MPPE is misusing CCP (compression
control protocol) for something for which it was never intended. The
specific place where this is a problem is that the compression code in
ppp_generic doesn't guarantee that it will never send a packet out
uncompressed, but MPPE requires that. How do you get around that
problem?

Paul.
