Right.  I think there should be less ports used, not more.  I had
mentioned before that if all sockets accepted a simple command before
sending their data, then only that one interactive port would be needed.
It would simply return the data requested by the command.  If command is
blank, then return everything like the current non-interactive ports do.

So does this diff idea assume changes since last sent?  Then it must
assume there is only one process receiving that data?  If the data is
being sent to multiple locations, then we could miss bits unless we
track the different destinations.
