I'm not quite sure - I'd have to think carefully about what you're
proposing and what lwIP supports, which I don't quite have time for at
the moment, but there should be a way to do what you need.

There is no active developer for PPP, so bugs aren't really getting
fixed at the rate I would like, but people use it and it seems to work
well enough for at least some of them, so I would say give it a go and
see.  If you're able to improve it, then fixes are very welcome.
