That's awesome dude, 2 feature suggestions:

Trigger based relay, IE: requiring a preceding 'command' for the relay to operate (perhaps an optional feature the preceding string could be a cvar if not set all are relayed)
example:
/scr this sends to other servers
this does not

if scr_start_command "/scr" or something along those lines.

Other idea is to include a command as follows
/admin

This could also be used in conjunction with irc relay to send a message to only admins on all servers with the relay as well as send a message to IRC.
