Hello,

Simply because nobody took the time to do it yet.

I don't think there is.

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.

It completely depends what "mediocre" means. I have seen so many levels
of it. 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.
