They can't go too broad yet, they haven't even delivered effectively on the original vision for TOH, longer-term they could look at something like 'grades' for TOH's.
If they get too "scatter-gun" in their approach, they'll never fully nail anything, they're already struggling as is...
Sill waiting on them to execute beyond NFC-triggered sw autoruns for their TOH's, that's not "unique/innovative", it's been done, is do-able in Android, & even iOS/WP.
The i2c interface* is there for a reason, they must leverage it far more than they have, so far...

*I hope they migrate to something more powerful eventually, but they're still far from getting the most out of i2c, so no rush
