Smashing Magazine: Browser Tests, Services and Compatibility Test Suites

I have been pretty busy with a quick trip to San Fransisco for a couple baseball games and siteseeing last week but today, I came across an interesting article about Browser Tests, Services and Compatibility Test Suites. Smashing Magazine seem to always have quailty posts. What stood out was the multi installs for IE and all the Browser Tests: Online-Services & Tools available. It would be interesting to add different browser version tests to a selenium ant. Or add Browsershots to a build ant for viewing the pages later.
