Amazing, this is practically what I implemented in Thuban (see sig for
URL).  It wasn't very difficult to do that by deriving some custom
classes from the ones in unittest.  Basically, skipped tests raise a
SkipTest exception which is recorded by the test result class not as an
error but as a skipped test.  The relevant code is in test/support.py in
which can be accessed with viewcvs as
http://www.intevation.de/cgi-bin/viewcvs-thuban.cgi/thuban/test/support.py?rev=1.19&content-type=text/vnd.viewcvs-markup

I think this would be useful to have.
