how to synchronize two G4s

[Malcolm Hamilton]

thank you to those who suggested various ways to keep a desktop and 
powerbook (connected by ethernet) synched up.  I want to be able to 
do this so that at the end of a working day I can update all the 
different files that I've worked on, some on the Ti, some on the 
desktop, and thereby keep both machines synchronized.  This, I think, 
will help keep me organized as I go from one machine to the other - - 
it will also effectively give me the all-important back-up we're all 
supposed to be keeping.

One of you recommended RsyncX  - - sounds very interesting.

Something else that has been recommended is called 
FoldersSynchronizer (http://www.softobe.com/products/flsy/pp.html), 
which also sounds good.

Has anyone tried both of these programs?  If you have, could you 
please tell how they compare?  I would really like something easy to 
use: one little window, one little button, one click (maybe even 
schedule-able?).  All of this may be too much to ask for, but here's 
trying!
Thanks for the advice -
Malcolm
