Of course it's not flawless. If it wasn't for you, just be honest and say so. Don't try to invent reasons why it won't work for other people. As far as I know, there are no population issues with ASSS. A few years back, Hyperspace was getting peak populations of about 100, and never experienced anything unusual. Hockey zone was getting even higher populations during their leagues, but I was given to understand that most of those were spectators. There were issues, back in the early days of ASSS, when HS was the only real zone running on ASSS. They were actually related to the number of packets being sent, which scales with population. This is like 2004-2005 era. I think that by the time Hoch wrote that (2006, you said?), they had already been fixed. Either way, they've been fixed now, and fixed for years. The reason most zones (TW, EG, DSB) haven't switched is two fold: Firstly, they are getting free subgame hosting from PriitK and would have to pay for ASSS hosting. Secondly, they don't have much in the way of active development that would benefit from ASSS. After all, there's little point switching (and paying) if you're not going to use the expanded features it offers.
