@horton, I've been emailing with one of the founders as well, and have been working on an android app to process and plot positional/speed/acceleration/pitch,etc data and plot it all with specific focus towards slalom skiing.
The hope is that one could 'map' a course simelar to zero-off and my program would process the data and split it into passes. It could plot and replay the data, as well as log it all to a database for comparison.
It will store sets by date/time/skier and will store relevant pass info like a ski diary, such as rope length, boat speed, pass direction, z-off setting, ski settings, notes, etc.
One day the hope is to correlate that with video data as well so you could select a spot on the pass and see the data for that point as well as the matching video frame (that part of the program isn't done yet!)
Unfortunately I have been having a tough time getting any info about the API from the manufacturer.
The competing product (Xensr) will be launching shortly too.
My program is currently able to parse/plot fake data from google maps (I'll post a screen shot in a couple days when I have my computer)
I was hoping to have the sensors integrated with it before sharing this all, but you guys are too quick for me!
Unfortunately my real job gets in the way, but I am hoping to have somthing available for next summer.
