I've setup rsync between three national systems that mirrored between
themselves, but this is not really a good design, rsync is unidirectional.
You can use it via a round robin like cron job between the systems. But
it will get in trouble if you add too many systems. Unison,
http://www.cis.upenn.edu/~bcpierce/unison/ is a better choice, it is
bidirectional. But it only works between two systems.
The best would probably be an Andrews File system to the desktop. But it
is a synchronous file system. If two people try to update the same file
at the same time, it used to be that the last write won. Now I believe
that some type of merger takes place. http://openafs.org/ AFS is secure,
works on many platforms and has other advantages too, like continuing when
disconnected and then merging when connected.
It's included in the kernel, Linux 2.6
