BrowserCam is a paid service that allows you to preview a site in many browsers, oses, and settings.
I've setup a Fundable.org group to raise money for 20 people to have accounts. It costs $25 per person, and each will have their very own account. Keep in mind that this service costs $25/day if done outside of Fundable.org. This is for the Capture and Remote service. If the $500 needed is not raised by January 14, 2006, you will GET YOUR MONEY BACK.
