Check Selenium Grid:

(..) Stop waiting hours to get the results of your web acceptance builds! Selenium Grid transparently distribute your tests on multiple machines so that you can run your tests in parallel, (..) this will dramatically speeds up in-browser web testing

Getting started it's very easy (http://selenium-grid.seleniumhq.org/get_started.html) and demo site is present too.
