Two things to add:

1. The best use of Tectiles I’ve seen to date are these on/off switch mats (they’re quite cool – but again, limited in who/what they work on).

2. Those NFC ‘tap for content’ things? I spotted them on SWTrains recently – http://www.flickr.com/photos/whatleydude/8439023580/

THEY’RE COMING.
