How fast should be the server to be able to perform this task? For instance, would PII/400MHz/128Mb be enough? Do different cards (meteor/bktr) consume CPU power differenly, or about the same? What is the video resolution which consumes almost 100Mbps? Is it possible to record video under FreeBSD? Which card should I buy for that? Is multicasting can be done using combination of available software, or some programming required?
