Well, almost. Dean Edwards’ IE7 Project is:

...an attempt to make Microsoft Internet Explorer more compliant when it comes to web standards.

Web developers are becoming increasingly frustrated at the lack of convergence of the major browser vendors. We need a level playing field!

Couldn’t agree more, Dean.

The code is currently in Alpha, but it already looks very cool. Currently supported are :first-child, :last-child, :hover on anything, and quite a few more complex CSS2 and 3 selectors. Sweet! One caveat - it doesn’t work in IE5. It does now!
