I have not heard of anyone porting lwIP to eCos, but it certainly would be an 
interesting project. It would also be interesting to see how much it differs 
from the OpenBSD port that is eCos native TCP/IP stack. By looking at the 
number of lines in the C code files, the eCos TCP/IP stack is about three 
times as large as lwIP (33k lines of code vs 12k lines of code).

The FreeBSD PPP implementation is avaliable under the same license-type as 
lwIP, but it is not particularly lightweight. Linux also includes a PPP 
implementation but it is licensed under the GPL. It shouldn't be impossible 
to make both more lightweight.

James Carlson has written a minimal PPP implementation [1] that only 
implements one option but is complete enough to be working. For some reason, 
the author recomends against using it to build a complete system.
