I got an id? how ps can stay free even if more servers are needed. Donators is not going to be a problem for 1 -2 servers. Maybe for many serevrs and bandwith like 100+ servers its going to be hard. So what to to. U make so everyone can dl the server application or an version of it anyway. The u have a master server how takes the client at first. This server only have a couple of functions. 1. Have a list of all availble servers that has beeen up for more than 3 hours or something. 2. Take the first connection from all the clients and then spread them to the other servers. 3. yadayadayada
There is more it has to do to keep it a persitent world but to spread the connections to local servers u get alot of benefits. This will need alot of planning in the code but can be done. This is the way u can keep servers running , and also get the clients to go to the nearest server. By making the criterias for login serevr be uptime and speed u can make som sort of promise the login servers will be up, bud they need to sync with each other all the time and maybe this will not work, I dont know....
