That's progress; thanks!  It gives me a choice of running either all 
tests in a particular class, or one test.  I could probably cobble up a 
shell or python script to wrap around it and allow me to run a list of 
"specs"; it'll be better than all the "foo"ing I've been doing. 8^)

A quick thought: maybe I could use decorators on test methods to apply 
"tags" to my tests, then write a script to run all tests with a given 
tag; this might be even handier.

Good advice, if you're distributing a python library.  In my case, the 
end result is an installer that creates a single .exe (a Windows 
service; frozen with py2exe) and a config.ini file.  For me, there's no 
particular value in creating a package hierarchy just for testing. 
(With one possible exception: I may want to create a multi-level 
hierarchy of tests, rather than just the fixed file/class/method 
structure that unittest/trial gives you.
