multi-Internet Explorer testing... a solution?

we just stumbled across this:

And on initial testing it looks like we may finally have a solution for testing in multiple variants of Internet Ignorer!! Yay!!!

Let us know if you spot any issues with it but we're loving it at the moment.

Now to find FireBug for Internet Explorer and we're truly laughing :-)
