Robert Love, a famous Linux kernel hacker, has written a blog entry with his thoughs on the recently posted Vista's network slowdown issue and the explanation given by Mark Russinovich: "Unlike DPCs, however, the Linux parallel does not consume nearly half of your CPU. There is no excusable reason why processing IP packets should so damagingly affect the system. Thus, this absolutely abysmal networking performance should be an issue in and of itself, but the Windows developers decided to focus on a secondary effect."

MMCSS is not integrated with the scheduler. It's a usermode hack. It's a service that runs with high privilege that adjusts the priorities of other services. It is not useful for a server and likely won't exist on WS2008.
You miss the point. The problem here is with Vista's networking stack somewhere. The MMCSS hack was implemented as a response to it, but all processes can be affected, not just multimedia ones.
