ie...
Server irc1.irc1.irc
#room1, #room2, #room3

Server irc2.irc2.irc
#room4, #room5, #room6

Everything on server 1 to echo to all windows on server 1, or to only echo to the rooms that the person is on, or... (?)

What you are asking is going to require using $cid and $activeid

ie..
Code:
if ($cid == $activeid) { echo -a $nick :: $1- }
if ($cid != $activeid) { commands but not echoing to active window }

You should get the idea from that.
