As I've been digging into Di2 with a smart phone and trying to show Di2 information over ANT+ protocol I have also found out, that you now can actually take someone elses Di2 shifting mode over and switch between manual, semi-synchro and synchro shift.

Other than that, I have yet to come across a google link that has been successful in deassembling the software from Garmin, Wahoo or the ETube Project Software to find the ANT private network key.
Sucks, especially with the possibilities of controlling the shifting from the smart phone and maybe write a program that automatically shifts for you based on power, cadence, heart rate and climbing delta rate data.
Ow well
