thanks for the warning.

i'm currently loking at eddie(http://www.eddieware.org) to do the load
balancing for me.  eddie can do a lot of things.  one of them is redirecting
request according to METHOD.  so, if it's a post, i'll redirect it to one
particular server.  if it's a get, it goes everywhere.  i would think that
rsync can update data from the machine that handles post request to other
machines.  so, in a sense, i'm using one Data.fs,  but distribute all GETs
to all available servers.  but i'm not quite sure of the update frequency.
