Remoting versus Sockets?

Question

Further to WoodenSwords thread on whether Remoting makes Sockets obsolete, does anyone have any further rules for which to use in general situations? I'm currently working on a user interface displaying real-time info to unlimited clients - I've started with remoting but feel that UDP would be the best protocol. However this would require me to write my own custom UDPChannel for remoting which is beyond me (is this strange that Microsoft have classes supporting UDP with sockets but not with remoting? I can't find any source code on the net for a custom UDPChannel - does anyone know a site where I can find this?). Have I made the right choice in TCP/remoting or is UDP/Sockets the better option? Many thanks Sid
