Yes, I am running Tiger. I could go the smart folders route, but wouldn't it slow me down quite a lot with my having thousands of documents?
Also, I'm wanting to purchase a notebook (recent "halo effect" switcher, currently with an OC'd mini), so I'd like to have an app that I could use on each system that has the data stored on a server. Not sure if smart folders would work with network data. I know that there is a hack to get spotlight to work on network drives, but it seems to be a bit of a kludge.
Forgive me if anything I said above is off the mark, I'm still a bit of an OSX newbie!
