The current status is that we want to migrate to lwip http://darnassus.sceen.net/~hurd-web/hurd/translator/lwip/ so as to benefit from its maintenance instead of maintaing the tcp/ip stack ourself. Lwip itself doesn't support tclass, but that's probably a contribution they would welcome. > 3.

What I'm sure of is that a "mediocre" programmer can work and become a better programmer, and having a programming goal helps with it. Samuel
