Perhaps this is infeasible for some reason, but why can't they just use a (higher performance) version of Selenium or something similar? 1. Use machine learning to identify page elements likely to produce AJAX responses. Not too hard to do this, especially if you actually render the page in (say) Chrome and use the 2D layout in addition to the 1D HTML/CSS as part of your feature set. 2. Use your (souped up, ultra fast) Selenium replacement to play with all those AJAX features. http://www.reasonablyopinionated.com/2009/01/how-to-test-ajax-apps-with-selenium.html http://www.reasonablyopinionated.com/2009/01/how-to-test-aja... ...on the third hand, perhaps they're thinking that anyone technically savvy enough to set up an AJAX site (or set up sitemaps or the like) can run this headless browser.
