You could try my "TIFF tool". It currently runs under Mac / PowerMac. The present version (1.1) allows you to view and edit tags one file at a time.
The version I am working on (1.5) allows you to make Watch folders. Any TIFF file moved into a Watch folder will have a batch action take place on it. Batch actions include assigning specific tags to files, searching and reporting for specific tag contents, exporting the TIFF to a PostScript file, saving a tag log for the TIFF file, etc.
A Windows version is forthcoming, as well.
And follow link to Software --> Development
Hope this can help you!
