We have several clients that make heavy use of Samba.  So, yeah.

About as many as NFS.  Only one uses iSCSI and GFS.

We don't have many users using Squid, the only one I can think of is a
client running a smoothwall system that is a commercial release that uses
Squid on the backend, IIRC.

I prefer to use Apache to Squid for caching, primarily because the config
is much less obtuse.

For example, at home I have my firewall set up to redirect all traffic
headed towards mirrors.tummy.com to instead go to a transparent Apache
caching proxy.  Getting 100mbps or gigabit networking to my house is *NOT*
cheap, but the cache means that I don't have to keep a huge directory tree
synced, but at the same time I often get data for installs or updates via
cache at wire speed.

My biggest concern is for installs.  I'll frequently go months between
installs, and then do several or a dozen PXE installs for testing or
whatnot.

Indeed, that is one of the most frequent cases where we get a request that
would dictate Squid.

Munin should be on pretty much every machine.
