sI need to do selective updating for multiple sites over limited links.
Some need daily updates, some weekly or monthy.
The length of time required to look for new files and then copy them to
all locations over the satellite causes the replication to fail by
timing out or taking up all the bandwidth. I want to change the
structure so that all critical information requiring daily updates is
in just a few folders, weekly updates for other folders, etc.

Is this possible in the current released version of SharePoint or possibly
the new version in Beta now?
