Sounds interesting.  It's fine to copy files between caches on
different computers.

I would be careful about doing it fully-automatic though.  If you do
it while polipo is running, you will want to make sure polipo doesn't
see any partially copied files.  This is explained in the manual; see
"Modifying the on-disk cache".  I have a feeling rsync may already do
this - i.e. it first copies the file to a temporary location, then
renames it on top of the old version (if any), but you would need to
check this.
