First, whether this is practical or not depends on the number of files
with hard links that rsync has to traverse. The technique used to
find the matching links is not efficient and slows as the number
increases. Also, if you only sync the pc directory you'll get
duplicate (but working) copies since the links that tie everything into
cpool won't be followed. If you include cpool in the same run with some
machines being backed up at each location you will hit conflicting
hashed filenames in cpool which may or may not break things.

If you have to use this technique it would probably be safest to rsync
only the individual pc directories backed up locally to the other site
and put up with the fact that the redundant files will be stored as
separate copies.
I'd consider it much safer to simply let each backuppc server back up
all six machines separately. That way the pools are managed correctly
at each location and you don't have to worry immediately if something
goes wrong with one of the servers or you want to replace the hardware
or software at one or the other locations. If you do not have time or
bandwidth for two runs to complete you might consider using only one
live server and making an image copy of its archive partition to an
external drive that is rotated offsite.
