Today (Jun 3, 2009) Adobe Labs published a tool that might be a great workaround for a problem web designers and developers have to deal with every day: browser incompatibilities and testing web pages on different browsers and operating systems.

Adobe BrowserLab is an online Application written in Flex that lets you specify a URL which in return is exactly rendered on different browser/os combinations. After sending the request and remote rendering of the page, you get a screenshot that shows exactly how your page is displayed in the browser in question.

Supported browser/OS combinations are: Firefox 2.X and 3.X (Windows XP and Mac OS X) Internet Explorer 6.X and 7.X (Windows XP) Safari 3.X (Mac OS X).

The service is available as a free, but limited beta version at this time.
