Aren't we missing something obvious here?  Shouldn't we be using some
sort of distributed technology like BitTorrent?

I'm sure I've seen distribution schemes that organise a tree of downloads
with a suitable branching ratio so that no one server is overloaded, and
I've also seen tricks for pushing out one copy which is daisy-chained
through many servers in real time so that everyone in the chain has
one input feed and one output feed, but everyone receives the data
at the same time, modulo a few seconds latency from end to end...

We need to be looking at more creative schemes in line with modern
distributed and parallel networks.  If it's good enough for the warez
kiddies it should be good enough for us.

I bet you with a few hours thought we could come up with a hybrid
scheme which pushed out updates over a hierarchy to a sufficient
number of 24x7 fixed-ip machines, from which dynamic unpushable
clients could poll and fetch updates from without a damaging overhead
on any one server.

We can't afford to use the old gentle methods.  The viruses don't.
We need to push updates out almost instantly.  Blaster went round the
world in 15 minutes.  We have to be able to fully distribute our
updates in 5 - efficiently, but not in a way that causes net
congestion on any one link.
