They're game ports. The appropriate FAQ, <http://www.linuxsecurity.com/resource_files/firewalls/firewall-seen.html#1.1> (which you should bookmark, if not already) points at 27910+ for Quake, and I'm pretty sure I've seen one or two such games using roughly that range. In fact, on a google search, <http://archives.neohapsis.com/archives/incidents/2000-04/0077.html> pertains - it's Half-Life. The distributed nature of the source-ports goes hand in hand with it being a game as well; I don't think it'll last long, as once everyone realises you're not responding they'll stop asking, so it's not a bandwidth-eating problem.
