The Problem is that you can't rebuild the map from a continuing
stream, This is the problem with Database Replication in general.

If you lose the stream for any reason you have to start again, which
is a nightmare.

Things that can be streamed like TV and Radio change over time and you
don't need whats gone before. If you miss the beginning of a 24x7 News
channel or a soap you can still work out whats going on about after a
few minutes. With a Map you have not got a chance.

Maps worry about quality. Streams don't

I'm not quite sure how your stream would work.

Theory Great, Practice don't work.
