I apologize since I haven't touched Irix since 1999, but I was fairly certain my
Irix 6.x systems had it.  Now they _do_ sell NIS/NFS as a separate add-on which
we _did_ buy, but that was just the server.  I thought the clients came standard.

You essentially need both.  The loopback mount, since that's what is what you
are browsing, and the filesystem with the .iso files, because

I've always been able to find binaries.

There's a million ways to run something on a server, but write to a client. 
Remember, you're using UNIX.  ;-P

Again, I think the QA department has a "false sense" of a loopback mounted .iso
file being the exact same as a CD.  Heck, dd a CD then dd an .iso file -- not
the same because an .iso file is just the data track format for ISO9660 Yellow
Book, not the entire CD.

NIS, Autofs, NSSwitch all there.

> Mac OS/X (well okay it's not really UNIX)

Hmmm, not sure there though.  BSD has an automounter, or maybe you've gotta get
amd working?

I've only limited experience with HP-UX (1995 timeframe).

All there.

> Tru64 (5.x)

All there.

The original GNU platform (I love how the media "trips over itself" wondering
why Sun is so much like Linux ;-).

Again, they should be available there too.

Linux/Alpha has always been the engineer's dream platform.  UNIX on an
ultra-anal RISC platform.  Ahhh ...
