blessdiff for the "full featured hexadecimal editor"?

I am trying to find some hex diftool which allows me to compare to documents in the view but also the internal differences like in bless so two bless windows side-by-side but with diff capability between the windows, at least for selection. I find the bless - A full featured hexadecimal editor could be the best choice here for the integration. Is there any difftool for hex-ascii view in any Linux distro?
