How to put DI2 internal on a Cervelo R3 BB Right frame?

[bruno2000]

I was thinking of buying a Cervelo R3 2012 frameset with BB Right.
I also have a Dura-Ace DI2 11spd 9070 groupset.
Before deciding ont the frame, I want to know how to put the DI2 wiring internal.

-I will probaly need a long battery holder that goes on top of the downtube
-make a hole on the toptube like I've done on my S2 before
-the BB shell is open so no problems there
-what with the DI2 cable of the front derailleur and battry holder?
-Can I run the DI wire for the rear-derailleur trought the chainstays?

Does anyone has a plan for this?
