Sure, some examples would be great. I'm not overly concerned with
performance either at this point if you're still tuning. I have two
servers primarily that I want to mess around with. They are for sphere
the little user/project/development management tool I'm farting around
with. I have an smtp server and an ldap server. Both are very small, the
smtp server for the mail management stuff and the ldap server for user
management. I contacted Clayton Doneley who wrote the javaldap server
code and he gave it to me under the Academic Free License. It works,
it's small and it needs some cleaning up.

Yah, I'm not much interested writing networking code so I'll take what
you and Kasper make! :-)
