UDP Networking Basics (questions)

Thanks for the extra info, Winni. I guess it does depend what you intend to use your network for, as to which ports you choose, although mainly I guess I was focussing on just use for games. I'm not so sure about the lack of use of UDP for broadcasting, as many other people seem to be saying that UDP is the way to go for most games these days. I certainly wouldn't want to live with the potential halting of transmission that TCP induces when it stops getting acknowledgments, for example, although otherwise it seems pretty nice. I think mainly if you don't need acknowledgments then UDP is the better choice.
