[IRCServices Coding] Restricted + Secure --> No Kick List.

[Dionisios K.]

Someone has made an SQL Database:

Ircd checks from this database if user is permitted or
not to join the channel. Allowed nicknames to database
can be added / removed with services command like
this:
/cs allowjoin-denyjoin #chan nick
Also you can activate or deactivate this feature to
each channel... 
If the feature is enabled only registred nicknames may
use /join #channel command anyway.

And this can be used for nicknames too. When you
register a nickname the nick and the pass are added to
the database. Then you can not change your nickname to
this registred one if you don't supply the right
password. Ircd checks from the database if the
password is right and then allow / deny the nick
change.
Also you can activate or deactivate this feature to
each nickname.

Of course this requires advanced services - ircd
collaboration.. 

Is possible for something like this to be made?
