Great project. I just started with a basic Garmin footpod on our treadmill with Zwift, but have done a few other minor "hacks" on some of our other home gym equipment.
I added cheap ANT+ sensors to our older Spin Bike and Nordic Track Ski machine, mainly to log on my Garmin but the Spin Bike works with Zwift. Both the bike and the Nordic Track Ski Machine took some tweaking to get the wheel diameter right in my Garmin, and I still haven't got it to pickup the cadence from a counter-dilled magnet I mounted in the ski.
I also added a cheap cadence sensor to my Kayak paddle (Vaaka style for $15) and am now logging water activities. Just make sure not to submerge the paddle :).
