Selenium 2/Webdriver has all sorts of great benefits but there is one big drawback: it doesn't support running on a grid out of the box.
Has anybody switched from using a SE1 grid to using SE2 serially and been satisfied with the results? I'm wondering if the benefits of SE2 make up for the expected loss of speed due to running serially. Is SE2 fast enough that it somewhat makes up for this disparity?
Alternatively, has anybody rolled their own parallelization framework for Selenium 2/Webdriver? It seems like it wouldn't be too difficult to create a primitive one that knows how to poll slave machines and distribute requests accordingly.
