I'm pretty sure all the software is already available. That's what Tom has been doing. Note that the iBike acts as the head unit so if someone got a Quarq, they could get the iBike instead of the Garmin, and the cost would be about the same. And you wouldn't need a Quarq, you could do it with the ANT+Sport PT as well.
Actually...all you really need is a powermeter and a spreadsheet.

The iAero +ANT Sport setup just lets you
sort of do it "real time"...
