I was just reading about the jpeg 2000 image format and was wondering why, 4 years after it was developed, no browsers that I know of support it. Let alone Digital Camera's...

Is there something stoping it's adoption?  What would it take to get it into Internet Explorer?

It seems to me that if IE doesnt support it, nobody will because joe user wont be able to view it.

From what I've read, it's far superior to the jpeg format but it's suffering form the "chicken or the egg" effect.  Its not supported because nobody uses it, but nobody uses it because its not supported.

Maybe somebody on the IE team is working on it?
