So, internet code and lan code are pretty much the same then? I don't think I could do it with my phone modem on the internet, but I might be able to use the code for a turn based game.
They are exactly the same, but i'm using a different, less bandwidth intense transfer mode for internet. However, i'm not claiming that it's the best net code there is...i know that it isn't, but i think it's "good enough(tm)". However, a phone modem will be a bit too slow for it. For a turn based approach, it should work just fine. But maybe a simple protocol based on servlets and http will do fine too and will cause less trouble with firewalls and routing.
