The whole argument I'm making is that after the initial implementation**,
streaming the data is a lot less resource intensive than what we are
currently doing. Perhaps I don't have the whole picture of what goes on in
the backend, but at some point the changeset XML files are applied to the
database. At this point, we already have the XML changeset that was created
by the client. The stream would simply be mirroring that out to anyone
listening over a compressed HTTP channel.

Of course it could then by propogated to other servers if the bandwidth load
was too great.

One of the clients to this stream might be Osmosis, saving off chunks of
data one minute wide and sending it to planet.openstreetmap.org, for
example.

** ...and I've always said I would be willing to impelement this if we
discussed it and decided there was a way to source the data in a technically
feasible way.
