Thanx for sharing this. Read most of the big thread about this on the Xsyon forums. This spells it out pretty clearly. As far as a bunch of people wanting a one server solution that is not easy to do unless you design the game for it from day one (at this point I'd say impossible). I think Jooky is very smart to start looking at options. Somehow at some point he will have to get us to divide up whether it is by rule sets or location or some other means.
I've seen lots of posts about folks wanting less safe mode mechanics so it probably seemed natural to add a more hardcore PVP server. Also seen lots of posts about ping and EU players, so again location would be a natural way of dividing us. Honestly, what will naturally motivate us is lack of land to build on.
There is also the flip side of this, after the initial boost in player population lots of MMOs bleed players. Merging servers would actually be a nightmare in some ways with all the construction in Xsyon. So having a plan in place is good, but avoiding server bloat is just as important.
