This is good.

Still good.

This seems like a really bad idea. If every user running a browser is doing
HTTP communicaitons X% of the time their browser is running, this means
that each browser will now be performing HTTP communications X+n% of the
time. So in one fell swoop, this technology increases each browser's
contribution to net congestion.

Is this just a persistent connection? If a web page is larger than the
packet sizes between the client and server, you certainly can't load a web
page in one shot (whatever a shot is).
