Wow, everyone is being really hard on Rhett!  Rhett, welcome to the 
list, we don't always jump down the throats of people excited to share 
something with us.

Sure, it would be great if there was One True testing system, and yes, 
it seems like much of what Rhett built was available somewhere in the 
Python testing world.  Maybe that means we need to do a better job 
promoting and explaining what we've got to offer.  Reimplementing things 
seems to be endemic to the Python world, so let's not dump all over 
Rhett for doing it.  Maybe his take on things is a good one that we can 
learn from.

And some of us have been guilty ourselves of implementing from scratch 
instead of adding to an existing project (*cough* figleaf *cough*), so 
how about we give Rhett a break and find out what he's got.  I agree 
with Mark: when a company with bottom-line business to worry about takes 
the time to open-source their code, it's a good thing.
