Hey,

Looks like I found a solution to this one as well, and turns out ESL is MUCH more powerful then I thought, I've updated the wiki page for filters if anyone wants to have a peek http://wiki.freeswitch.org/wiki/Mod_event_socket#filter

Short answer, filter Conference-Unique-ID $ConfUUID

Good catch. "Unique-ID" is the header for a channel's uuid. "Conference-Unique-ID" is the header for an active conference's uuid.
