Why did you compare lwIP to Linux? Skipping throught the paper, I did not see 
an answer to this. Nor did I see an introduction to what is lwIP (Linux should 
be known well enough to not need this...).

Conclusions for lwIP are mainly:
1) less features than linux
2) not suited for multithreading
3) the tcp_receive() function is too complex

As to 1 & 2: this is well-known and intentional.
As to 3: reading (or debugging) the sources, this is obvious :-) Sadly, noone 
has volunteered to imrpove it, yet :-(

Oh, and I was both glad and amused to read that CC seems to serve no real need!
