Regarding the compact crank, I'm in two minds - 11-36 is very irritating to ride on the road. But if it reduces Q-factor I like it. I'm guessing the DA mech would need to have a long cage conversion as my road bike one will only take 11-27 and a compact. So figure another $100 or something.
This looks promising. Wonder what cage they are using?

K-Edge will sell a Complete Ki2, Di2, XTR Kit, including the Di2, for $4995 (this meant for mountain bikes).
K-Edge seems to be delving deep into modification of Di2. If we were to have any hope of the Di2 FD and system being modified for a triple, perhaps it would come from this quarter.
Ryan at Calfee showed me a prototype K-Edge FD clamp labeled as for triples mt bike/tandem, which brings the FD out further from seat tube so as to more easily reach the big ring. I am having it tried out on my bike, as I really have to push on the lever to get it out there. That K-Edge should include this product in their line of clamps shows they are at least thinking of solutions for triples and tandems. It is really frustrating that everyone else in the industry reacts to developing something for a triple as does Count Dracula shrinking from a crucifix.

Ritterview,
Do you know what cassette and chain combo Calfee is using? Is it Dyna-sys and XTR chain or Dur-Ace chain or is it SRAM XX and Dur-Ace Chain and or SRAM chain?

K-Edge has been great to work with. They helped me last fall to adapt their K-edge to work on our Calfee and are now making us a triple clamp as described by Ritterview to better integrate and on top of that are making it blue to match our bike. Kudos to them for incredible customer service.

I would love a FD clamp that puts the FD out just a tad more that the standard clamp, but much less than the FSA "tandem" FD clamp.
The FSA one will nut let me into my granny, the standard just barely gets my into the largest gear (right now 56x11)
