Well, I did find one way to speed things up. An "info" request of the 
file on the tag is relatively fast, and includes the "last change 
revision" of that file. I can then do a log of that file on the trunk 
(Which is faster by magnitudes), and anything after that revision can be 
considered a change after that file was originally tagged.

Anyway, I'm still open to any other advice on the matter.
