Mike Droettboom has experimented with py.test a little bit while working 
on a py.test plugin for Pandokia. He reports that it's not quite so 
compatible as all that, ie, there are useful test extensions (such as 
module-level setup and teardown) that are supported by nose that py.test 
does not handle correctly.

Mike, do you want to say more about that?

Also, I meant to report back regarding the status of nose that I got 
from the TiP folks a bit ago:

- the primary developer of nose, Jason Pellerin, doesn't have time to do 
very much, but there is starting to be more maintenance activity and 
contribution from the community on the nose-dev list 
(http://groups.google.com/group/nose-dev).  nose 1.1 was released at the 
end of July

- the plan is to move to a BSD-licensed nose2 package based on the 
unittest2 plugins branch, but that unittest2 branch is on hold until the 
unittest2 developer (Michael Foord) can get back to it.
