Path to rsync Binary?

[dmaloy at provide.net]

I am using rsync between to Solaris machines.  One has
rsync under the /usr/local/bin/rsync location and the other
under /opt/rsync.  Is there a way for me to issue the rsync
command from the "source" machine and tell it as part of
the command where rsync is on the target?  If not, does
this mean that in order to perform the sync between two
systems that I need to have a 1:1 relationship of where the
rsync binary is installed?

Thanks for the help in advance.
