I don't have time to get into a protocol re-engineering session but it
is simply untrue that it is impossible to push information to multiple
places using HTTP.

I think that someone else made the point that there are better ways than
just spewing UDP packets and hoping. Maybe you shouldn't be using a
packet switched network to start with! Anyhow, nobody considers HTTP a
replacement for UDP.

Quake players think that they are surfing the web? I don't think so. If
you aren't using URIs then you aren't using the Web. If you're using
URIs but in a protocol that makes it hard or impossible to resolve them
then you're using the Web but not to its potential. The same goes if
you're using URIs but also using a bunch of private naming conventions
in method names.
