Actually, that wouldn't work as there doesn't seem to be a way to specify tests to skip (only tests to run). Two other items though:

* Use the '@unittest.skipIf' decorator
  https://docs.python.org/dev/library/unittest.html#skipping-tests-and-expected-failures
* Add documentation on this so people know about the option/how to enable it/why it exists
