Harlan: have you actually _measured_ the amount of CPU utilization
that a network stack uses in a typical server environment for games?
Without that, any talk of acceleration is sort of pointless.  As
others have said, it doesn't look like there's much of a gain to be
had with acceleration.

FWIW, last I heard DirectPlay had been deprecated and was no longer
considered being pushed by Microsoft.  OpenTNL has some adoption
with open source, but not widespread adoption.  Most people still
roll their own layers or rely on the layers provided by their engine
provider (e.g. Unreal, Quake, etc.).
