I know it's not quite what you meant, but Cervelo have built a bike around them...well at least the front end:bloody hell! you could start with those and build the bike around it!
Not completely cableless, but if you want to use the Campag levers, there's a cable operated piston/reservoir option:If I could crowbar a reservoir and plunger into a Campagnolo EPS lever, I think it would make a great - and cable-less - build...
