You can't view HTML in repositories on bitbucket. This makes me sad (I want to display this: http://bitbucket.org/ianb/doctestjs/src/tip/docs/index.html).

Admittedly this would be a big XSS attack vector. But it would be nice if you could display all files in a repository (no content-disposition) at perhaps another separate domain, where no logins or actions could occur (hence no XSS concern). Like, oh, bitbucketfiles.org, or probably some better name I'm not thinking of now.
