Well, i guess i could have every client that "connects" send a "yup, i'm here"-packet. However, would this mean that every client would have to send something to the server every time they want to receive something?
Also, yes. My choice of words was inapropriate, since the data isn't really a stream. It's just so many small packets that it makes more sense to me to look at it as a stream, rather than packets, hehe.
And as for reliability, it's not really important. The data to be sent is calculated very often, due to changes, so reception of all of them is far from critical, as long as a majority of them is received. Also, the data will only be sent over a LAN anyway.
