Topic: My day job...
So, in addition to the stuff I'm working on for Chumby evenings and weekends, I do a lot of mobile app development during the daytime.
One on my iOS apps (Piper) just went live on the iTunes store - it's app that uses iBeacon technology to set up chat between iOS Devices. it also allows you to set up physical iBeacons and Qualcomm Gimbal beacons and assign content to them like web links, Facebook pages, Twitter feeds, photos, etc.
If you have a compatible iOS device (4S, 5, 5C, iPad 3, iPad Mini, iPod Touch 5, with iOS7), please give it a try! (Of course, you'll need to have a friend use it too..)
It's in the process of being indexed for search - in the meantime, there's a link on the site page.
I'm working in the next revision so now's the time for feedback!
