Chicago Mobile Meetup - Open Space Technology Format

We're going to try something new for this month's meetup, something that I hope you can all get excited about and join in to try out with us.  The meetup is going to follow the Open Space Technology format that is widely used throughout the world.  Here is a snapshot of what Open Space is from Wikipedia (http://en.wikipedia.org/wiki/Open_Space_Technology): Highly scalable and adaptable, OST has been used in meetings of 5 to 2,100 people. The approach is characterized by few basic mechanisms:

a broad, open invitation that articulates the purpose of the meeting;
participant chairs arranged in a circle;
a "bulletin board" of issues and opportunities posted by participants;
a "marketplace" with many breakout spaces that participants move freely between, learning and contributing as they "shop" for information and ideas;
a "breathing" or "pulsation" pattern of flow, between plenary and small-group breakout sessions.

The broad topic for the meetup is obviously to talk about mobile technology -- to learn and share our ideas and experiences with others (that takes care of #1).  We will set up the room at the ITA in such a way that should provide for the ability to move freely around the room and share ideas, learn, and contribute at your leisure.  Now, the only thing we need are some ideas for the breakouts.  I'm looking for ideas from the group for, say, 4 breakout spaces.  Please submit your ideas to the group and we can "vote" on the ones everyone wants before the meetup.  Here are some ideas to get the ball rolling...


mobile device management
cross-platform development tools
mobile web vs. native apps
mobile security
others ???


Looking forward to hearing your ideas!
