rsync might not be usable, but copying everything as soon
as anything changed is not a good algorithm imho.

On a sim with 15,000 prims I'm pretty sure there are
constantly minor changes - an elevator, a door, an ad
somewhere - the pet of someone - or the land is group
owned and people can rez/move things.  It is extremely
likely that -say- 0.1% of the prims changed position
or (dis)appeared. No need to re-download the other
99.9% too then :/
