Hrmm, I'm really interested in this.  The reason I started poking around
with Apache 2.0 is that I am writing a buffering HTTP proxy to allow a
higher request rate between Apache 1.3 servers and clients on
connections of varying speeds.  Clearly I would rather leverage solid
open source code than maintain my own.  I remember hearing that async
i/o isn't going to make it into 2.0, but if a third party (bind) comes
up with something nice that can be generalized for Apache, that would be
a huge leap forward for HTTP server technology.
