Well, you can determine it from the user-agent header: IE6 and Firefox are capable of client-side-transformation. Sure enough, the logic would need maintenance from time to time.

IE6 can always do transformations? I was under the impression that you could only do it after you downloaded the MSXML stuff. Either way, it doesn't sound too complicated ... 10 lines of code maybe? I'm not aware of any filters floating around that already attempt to do this, but I may be wrong -- it happens.
