Aside from this library, I'm not aware of a library like that. While I think the idea has some merit, there's a couple of problems: - Its a lot of Javascript, and that can make things really slow. As another commenter pointed out, the computer running IE6 is probably on the older side anyway. - Its a lot of work, and people would rather spend the cycles getting people to upgrade. To borrow a phrase, it would be rearranging the deck chairs on the Titanic. - Its sure to cause some quirks that in turn require their own workarounds. While older versions of IE are a PITA, their quirks are at least finite and known. Regarding AJAX, IE6 actually has fine support for AJAX. Perhaps someone can correct me here, but I believe IE actually introduced the XHR, which is the foundation of AJAX. That's not to say it couldn't be done, or that it wouldn't be fun to try. Those are just my guesses as to why we haven't seen one.
