Bi-Directional rsync

[Rylan W. Hazelton]

I have been running rsync on a number of my servers for quite a while,
but up until now, I have only been doing a 1-way rsync.  (ie:  1 server
is always the master/original and the rest are only slaves)

I have searched high and low and cannot find any information about using
rsync to do a Bi-Directional rsync.

Can it be done?  Can anyone help?

Thanks!

Rylan
