We manage a small squid server farm.

We have defined hostnames like "proxy", "proxy-sibling1" etc to
/etc/hosts on all machines with proper IP's and use there in squid
config file for directives like http_port, tcp_outgoing_address, cache_peer
and udp_incoming_address.

Now we have nearly unique config file - the only directive that differs
is unique_name. Even this mmight change, when squid stops deriving
unique_name from visible_name, see:
http://bugs.squid-cache.org/show_bug.cgi?id=2654

When we change acl's, we distribute new config file (maintained in svn)
to all servers and issue reload.

We do not share caches not logfiles - that would take some work to
maintain.
