Ushahidi v3.X is designed to include sensor feeds.  To see how people might use these, the Ushahidi team have been:

• talking to the Brck team about feeds from Brck to Ushahidi, 
• looking at available sensors and sensor types,
• looking at online sensor datastores (and how to access them),
• looking at sensors in the equipment around us (e.g. laptops and mobile phones)
• checking out work on sensor feeds in other communities,
• working on how to present sensor data in Ushahidi v3.x
• blogging about sensor ideas
