I've posted bnbt in here somewhere. It works fine, just make sure you have your bnbt.cfg file in the same directory as the bnbt executable. The package I made was called Puptracker but I haven't looked at those scripts in ages and I'm sure they may be buggy. Of course Azureus has a simple tracker setup but that requires java which is big and a resource hog. I plan on someday rewriting puptracker but you may get it to work.
