a) your question is still ridiculous? Visual Basic could be used if you have enough servers.
b) the place you are asking this question is ridiculous. It has nothing to do with game development or jMonkeyEngine… you are better off asking in a totally different forum.
c) I’m really sure that you have a client with 1/3rd the entire population of the internet as clients… even Facebook only just breaks 1 billion users… and in your experienced wisdom, you ask a dumb question on a game development forum.
So either you are as dumb as a brick and have a wild fantasy life… or you are trolling.
Either way, I’m going to close this thread now… it’s becoming more tedious than fun.
