Sorry, spark.io is down and I'm not sure what it is: A dev-board? Why not use an RPi instead of an arduino for something like this? costs ~ 25-35 USD (depends on model) + a WiFi dongle and you can write code in Ruby/Python?!

Spark core is a low power ARM Cortex M3-based board with WiFi onboard. Very neat.

I can give you several good reasons why it is more useful to do this with a Spark core (or an Arduino), but the most important to me is that learning how to program very constrained hardware platforms is useful.

There might be a market for an e-paper based version of this that shows an entire day or week of schedule.

I've been in a few buildings where each door had a fat 15" LCD screen mounted beside it, displaying current and upcoming reservations. Even at my university they were beginning to implement them. You probably need good connections with commercial builders to compete in that space, though.

Way back before the WWW my student dorm door was plastered in misc comics and clippings - I kept cycling the clippings and being part if a high traffic corridor it got me a number if interesting people knocking to say they enjoyed it.

It was I guess my first blog (maybe Pinterest)

Anyway, besides that I think this really would be a fantastic solution to the "meeting room" problem.

Book a room direct from the door itself - seems natural to me.
