Q: server or workstation

It can be installed on a macpro without server.

I ran it on a Quad G5 at one time and it worked fine.

You will miss out on some features but it is definitely doable
and would be an easy way to evaluate it for your workflow.

You won't miss out on any features, you'll get everything on a Mac Pro you'd get on an XServe, FYI. The app is the app, no matter what it's in stalled on.

unless he is speaking about OSX Server... not OSX

For most smaller setups OSX will be fine. For enterprise with easier
mail deliver (review and approve) and other advanced tools then
Server would be your best bet.

Again, you'll get the exact same full feature set in FCSvr no matter which OS you use. Server makes larger groups of users easier to manage, and is required for a SAN network. Everything else is exactly the same.

I have recently set up FCSvr on a workstation running stock OSX 10.6 and it seems to run fine. You may e-mail me privately if you'd like to discuss in detail.

I have several clients running it stand alone on FCP systems, using a RAID storage device (eSATA, or Fibre), simply to catalog assets, on OS X, no server involved. It emails automation emails just fine. Server does nothing but allow group/user management for large organizations, a little more security. And now with ActiveSAN, you don't need OS X Server for SAN anymore.
