Been out of the Live loop, Underfoot is the most current expansion at the moment yeah? So when this becomes compatible with EQEmu we just sit and wait for the next expansion to be released and begin work again? Sounds pretty great to me.
I am by no means and expert on any of the server side stuff, but i do have a rather off topic question. I remember reading something about everything up to a certain expansion (maybe Luclin) was good to go when being used. Zones were pre populated all you had to do was load up server and you had yourself a classic server set up. After that point though, you have to use a packet reader to populate your zones with live content.
I could be completely mistaken, but have been curious about this for a bit and never really asked til now. I imagine a few could answer it pretty well if they care to
PEQ is prepopulated up to LDON
You can also download .sql files to source in new zones from here

They have been collected from Live however they don't collect the full spawn rotations, only what is currently up, they also don't have correct hp etc and no loot tables so it still requires some work once sourcing. However it saves you the time of doing most of the spawns and it places all the doors/objects/elevators etc for you. So it makes life easier, although it also has a habit of collecting people's horses that were being used at the time...
