I am working on a c code parser written in python right now.
My main focus is parsing .h files to generate wrapper code for python 
(yes i know about SWIG), but i hope it will do a lot more, such
as general "explaining" that you (and many others) would like.

highlighting external traffic to sockets is somewhat specific,
but my hope is that a well written python c-parser will allow for
custom extensions without to much hassle.

let me know if you're interested; i'll announce something on c.l.py 
soon i hope,

cheerioh,
