another concept that wont be realized anytime soon but is doable
the idea behind this is to run a mod like crossfire on 2 or more servers
-> sirius on server 1
-> altair/inner core on server 2
basically if you go through the rift your chars will be saved and moved to server 2... then you simply log off and go to server 2 where your chars will be waiting for you (of course you wont be able to use the chars on server 1 then)
advantage:
no need to use altair systems on server 1 -> less lag in sirius
no need to use sirius systems on server 2 -> less lag in altair
just one client version which has both altair and sirius is needed -> no need to change mods
possibility of alliance clans and coalition clans (raids)
more players on CF/less lag
if one server is down you at least have the chance to play on the other server if you have chars there
disadvantage/needs:
2nd server is needed
heavy coding is involved
