As someone who's been using push before anyone knew what it was
(1992), I wonder about this notion of mail as push.

The idea of push is UNSOLICITED transfer of messages.

Mail, Pointcast, etc. are _subscription_ messaging services.

We implemented push here, both unicast (LowLat) and
multicast (LSAM). and

The primary problem with push
is that it eats bandwidth, and companies seem to
not quite understand that it matters _where_ in
the network system you deploy it.
