New to this list and have only recently started building an
interface to 0MG so I want to check my understanding.

RTD Server == Real Time Data Server (?) and is there more
to this than just a real-time data feed?

C10K Problem == 10000 clients on a server (?) and is there
more to this than optimizing for concurrency, e.g., to really
take advantage of (say) an 8core system with 2 ethernet cards
w/ 4 ports apiece?


XMPP is there more to this than supporting instant messaging?

Just trying to put some flesh on the discussion :).

Thanks
George
