Did you benchmark the two stacks?  Perhaps a definitive performance benchmark 
is the way to make this choice.  I had to make this choice and chose lwIP even 
though I have to develop the Altera TSE port (no one seems to have done it).  
The port is difficult because the hardware API is married to the Interniche 
stack (the HAL APIs use Interniche data structures) and Interniche is married 
to uC-OS/2 (delete uC-OS/2 in the IDE and it deletes Interniche too).  Most 
reports have it that the "SUPERLOOP" mode doesn't work.  I'm not using sockets 
and NO_SYS (using a cooperative tasking system instead) and counting on the 
lower level lwIP implementation being more efficient.  If I'm correct and it 
is, why wouldn't lwIP sockets be more efficient than Interniches?

If I have time to benchmark, I will, but it's not apples to apples.

Maybe Jifl can clarify the statement he made because it does sound shocking.
