Watching the Watchers
Just a random idea off the top of my head... it would be sweet to have a modular, updateable firewall system, that I could put on my router at home or work, which would intercept these "phones home". It would send me, the owner of that information and the tattling device it came from, an email with a full report. Perhaps with some anonymizing function that tells the publisher "Just reading page 129 of War and Peace again! Send OK certificate so device doesn't lock!"
