I would have to disagree here.  Sharing a filesystem on Unix is pretty easy.
I've never tried to share a database, but it didn't seem easy. Of course 
that
may just be the learning curve.  Once you know how to, it may be easy.

In our industry (GIS), it is not uncommon these days for datasets to reach
several hunderd Megabytes, with multi-gigabyte datasets from time to time.
Keeping track of these as in Bugzilla as attachments won't work for obvious
reasons.

What we've been doing is placing them on a shared drive on our fileserver in
a directory named errdata, with the subdirectory for each bug (named using
the submitters initials (out of tradition from our pre-bugzill days) 
followed by
the bugzilla id).  The only thing we put as attachments are things like
screen-shots.

I wrote a script that fires off via cron every night which looks for bugs 
that
have been closed for 14 days or more which still have data in errdata and
delete it to keep from accumulating old data.

I'd like to be able to manage this errdata directory via bugzilla, but I 
think
doing so in a general way is impractical.

That's actually been implemented in 2.19.3 if that helps
