That idea is really cool... other featues could be having your name in a different colour (I mean, f.ex, when you put your mouse on s/b, it shows his name in white, but if that person is a donator, is wrote in yellow).
I was curious about how \'the 4th coming\', another free mmorg, was doing, and I have discover some interesting things:
? at the beginning there was Vircom who made the code
? then they wrote a licence (which I have not found so I do not know what it says)
? then they offered their product to companies
? those ones run dedicated servers, under their own conditions
The result is a game where, with one client, you can play in many servers, some free, some not, each one with different carasteristics (I mean, different religions, politics, and so on, but same races and world) and even different languages.
As you can see, the concept is not the same than ps\', but I definitely find the idea of another company hosting the server for free the best. Whch don\'t exclude unique items for donators.
I think, what if, for connecting, you should go through a web page that the server company would control?
