I'm currently w/o connectivity but there is a documentation on generating 
patches for Mahout on our wiki page (click on documentation from our main page 
to get to the wiki and search for patches there).

Agreeing with Hector that if your implementation is more general you really 
should just change the existing version instead of creating a new 
implementation.

Looking forward to your comparison.
