If you wouldn't mind, I believe this would be an invaluable tool for
myself and others doing performance tuning/testing.  Especially if it's as
easy as adding a package.  I'll be away for 4 days for a wedding.  Can you
email me any results from tests with an updated ule along with a package
or a tar of any scripts/setup you have?  Then I'll be able to hack away at
this when I get back.

Thanks,
Jeff
