Wait a sec, is that all they're doing? If so then that's really lame. What I assumed from their product description was that they're running all those browsers in VMs or some-such in the same way that browserify.com, crossbrowsertesting.com and browserstack.com do. That would be very cool to have as a local service but quite hard to pull of in a way that's nicer to use than just running a bunch of VMs yourself (which is a bit of pain). Massively overselling your product isn't a good idea. If they sold it as what it is then maybe that's useful to someone. But implying that it is more than that just makes it look really really lame.
