R-Name is a free batch file renaming utility. You simply drag 'n drop files (or folders) onto R-Name and they are automatically renamed based on your settings. You can even preview the changes before actually renaming the files. The source code is available.
MCHERVE an unofficial UniversaryBinary can be found here. I don't make any support but it seems to work both on PPC and intel. Enjoy (and read the ReadMe ;)) bye
