Here's the kicker - if the hardware is a single processor - how can a server be a true "mutli-thread".

Am I over simplifying (or just plain ignorant - a good place to be these daze). I "think" the only advantage of a MTDLL is how it consumes memory (on a server). With MTDLL - one address serves all clients - is this correct?
