I knew you would say that! ;)
The source code is at http://arturs.iidea.pl/server.py
and you can get 'live demo' by
$ telnet arturs.iidea.pl 2211
It's based on simple chat code.

I just want to keep this one little global, userlist, in order
not to do some strange acrobatics later. It's clean, simple,
keeps the number of arguments to pass to ther functions small etc.

In this case it fits perfectly. I need to acces userlist from any place,
any moment.

OK, suppose I want to do away with global userlist.
I want to pass it to TS_Command instance. Will it work? No. Why?
I have no idea... You see, I don't want to stick fanatically to my
global, any solution is fine, provided that I can split my code
and see it working as before, when it was all in one file.
This 'userlist' is my last obstacle.

Regards,
Artur
