The reason why group communication software is used is simply because
this software is designed with two goals in mind:
1) optimize bandwidth usage
2) make many-to-many communication easy
Number one is done by utilizing things like multicasting where
available.
Number two is done by using global scoped queues.
I add this only to avoid reading that pushing some PITR log snippets via
FTP or worse over a network would do the same. It did not in the past,
it does not do right now and it will not do in the future.
