Looking for Android based scouting, no wireless, little cellular

[fovea1959]

We've been using Wildrank for the last 3 years or so with good luck. The team purchased 7 Nexus tablets to use for it (they have bluetooth and 802.11b, no cell), and Wildrank transports the data around via a thumb drive passed from tablet to tablet. We use someone's phone to download the schedule from TBA when it comes available, load up the tablets, and we're good for the weekend. As I recall, data was in JSON format, which made writing our own rollup/analysis a cinch....

We've had good luck with it, and it seems customizable enough from season to season.

We're wanting something just as customizable as Wildrank that doesn't have the requirement to pass around the thumb drive. Since you can't count on having 802.11 at a venue, that means Bluetooth, cell (which our tablets don't have), or magic. Having to have a non-tablet server to consolidate data would be fine.

I've been looking for Android based scouting systems that can use Bluetooth to communicate. So far I've found Scoutr, Thunderscout, FRC Scouting Radar, and FRC 2729's system.

Any others out there that are available and meet the criteria (Android, open source, no cell necessary after start of competition, customizable from year to year)?
