wp.com highlander comments – plugin?

I just realized, wp.com users have this new highlander comment system:

anyone know of anyone who’s ported it to a plugin for non-wp.com wordpress installs? or something?

i would LOVE to have this in my site.. I’m sick of the disques & facebook comments that you can’t completely stlye because of the use of <iframe>‘s and fb’s recent dropping of custom style sheets… by the looks of the source code, it seems there shouldn’t be an issue style’ing any/everything.
