You have all the source, go for it :-). The net stack does have 
documentation. See http://www.vsr.si/ecos/ for example.

As for memory management. eCos generally just sets up the MMU in a simple 
way. There's no protection between threads (i.e. no processes) nor 
separate address spaces.

Although 3G Lab did some work on this for StrongARM: http://www.3glab.org/
