This is pretty cool. I wonder if something like this could be put in an ant task.

Glad you found the talk useful. Generally this is an asynchronous process, but there's no reason you couldn't start it up from an ant task. Mogotest (http://mogotest.com/), the commercial system I've built around this, has an ReST API you could use for that. We're looking at adding tool integration for the more common tools to make that simpler.
In any event, I do finally have http://webconsistencytesting.com/ online if you're looking for some more information on the techniques discussed in the talk. There's also a Google Group up if you have questions and what not.
