Copying an idea that WoW uses for its PvP battlegrounds and such... They literally pull people from numerous servers into quene times for these PvP events. People choose which event they want and wait, sometimes as little as30 seconds to start an event.
Would it be possibly to do this with Raids in EQ2? Basically have someone start a Raid quene for a particular instance and then people could sign up depending on what class is needed. Then if you pull resources from numerous servers, then you should be able to form a raid fairly quickly during peak hours.
Just thinking...
