Sure! I've actually been working on something for SocialBizUG to showcase the solution we're working on. Being that this is a pet project for me, I can only put in a couple hours here and there.
That said, I've gotten quite a lot of solid feedback for both the room signage (2 iPads) and the “web app” which we deployed to over 200 iOS devices. Users are clearly finding this information very handy, so it is well worth sharing!
