Not going big at all. I'm not planning on having more than a couple dozen people at most.
I also don't plan on loading all zones statically - just cities and the most often visited zones (maybe 30-40 static zones, probably less).
So why try? Just to see
Oh and I really did want to go linux but I'll also be using the server for development under the Lawmaker engine and lawmaker is pure windows. Perhaps when I've got an app actually built in lawmaker I'll see if I can get it to cooperate with linux but until I'm entirely comfortable with the sdk I don't want to be sitting there trying to figure out if the problem is lawmaker or my linux setup.
