Yeah, I came across those two in my Googling before I posted yesterday. They look like the two best contenders out there. Check has the advantage of being much better documented and having better options for output of test results, along with an easy way to organize test cases into test suites, and call those test suites from a single entry point, which is something we really want for our nightly build tests. Seeing nothing better out there, I'll give check a shot.
