Pretty much, yeah! When that episode of The Office aired we all emailed each other - it was pretty hilarious. Of course ours was a bit more pragmatic, it would only send to the medium that would best get in contact with you - and you could use it to bulk send messages to your friends. A tool like that doesn't really need to exist in this day-and-age as everyone always has their cell phone and modern cell phones are super-capable.

For reference, the clip from The Office: http://www.youtube.com/watch?v=ytc9-wGCHW0

That's awesome. Facebook seems to be trying to do what you did with their new messaging features. I'm sure it's totally different in some fundamental way but interesting that they went there.
