I agree that it isn't the easiest build machinery, but I actually like the
way you can use one source directory and send up different build directories
for the different java libraries, VM and compiler combinations.
You can run each test individually though by using something like:

echo | \
  SomeVM -bootclasspath SomeClassLib gnu.testlet.SimpleTestHarness

(This assumes you have used the choices script to actually compile the class
with SomeCompiler :)

My script referenced above does make a couple of these things easier, but
I don't know how portable it is (it works for me with bash).

You can use multiple files for a test. You just have to make sure that
a test lists all source files in the "// Uses: " comment. It would be nice
though if you could list source files from different packages though.

On a related note, we should also add a tag "needs internet connection" since
some tests can onlt succeed when you can access some (random) machines on
the net.
