Exactly. After all, for lwIP, SLIP is only another netif and the current 
implementation happens to be blocking...

I wouldn't know exactly since I didn't yet _use_ lwIP PPP (only browsed 
through the source code deciding not to try it :), but isn't the 
existing timeout management of lwIP enough for PPP, too?

I'm afraid I don't understand that question? Is pppd (I assume you mean 
the *nix one) mentioned there somewhere? I'd guess it could be used 
against any version of pppd as long as you run that with the correct 
settings (which can get quite complicated).

You mean lwIP PPP, right? The sad answer is: no. Since none of the (4?) 
active developers seems to be using it, the only active development 
currently is coming from 'users' on lwip-devel or lwip-users sending in 
patches.

I guess we'd all be happy to see someone working on lwIP PPP: any users 
wanting to become active developers + maintainers for this part are of 
course welcome!
