The .mo files are just generated from the .po's, so that doesn't seem so 
useful. To be honest, I didn't say any more specifics because none really 
came to mind. Diffing MS formats would be great, but we'd probably want an 
external utility to do that for us. Diffing the file listing of a tarball 
might be useful (and I'd really like to see if those drivers can be made 
non-app-specific - Gollem could use them too). Not sure what you meant 
about directories?

Cool.

Wherever it can be re-used... Glad to see I'm not _entirely_ predictable. :)
