Hey guys

I have two questions that have been puzzling me, I was hoping anyone could answer them please.
1) EQEmu currently requires EverQuest Titanium to work with, eventually when development expands to work on following expansion packs, will players be able to play EQEmu just using the Titanium pack still, or will further purchases be necessary to play?
2) If EQEmu ever shuts down, will player servers still be accessible & playable?
Thank you very much!
