When test results were added Tony and myself talked about all kinds of
interesting ways we could farm information from those results.
Regression detection via test results is one of the interesting ways
we can use the data in the appdb.  Basically we could look at the test
results across differing versions of wine and look for cases where the
rating decreased while the wine version increased.

Another interesting one that I thought would be useful is to look for
discrepancies between the results of the same application and version
and same wine version across different linux distributions.  We could
look at this on a large scale to see if some distributions had more
problems than others for the same versions of wine.

These are both pretty easy to implement.  If anyone is interested in
doing so and would like some assistance feel free to email me.
