Tim - good, you've made your goal clear.
Now lets focus on the process. I'll explain a couple things briefly, given your stated goal:
1. You must have MC configured to write out tags so that this metadata follows the files. Confirm your settings. Confirm also that the files have the tag values written (use MC's tag dump in the Tag Action Window).
2. Your media files now need to copied to all the relevant systems.
3. On the target systems, import those media files into MC.
4. On the target systems, create a new smartlist, hit the Import / Export button, and type (or paste) in *exactly* the same data you see in the same location on the source system. If your smartlists make use of path-based rules, you'll obviously have to adjust your paths to reflect those on the target systems.
