living in the future today
What way do you want to work with your computer / media and communication appliance / ... / house in the future? It may already be possible today, if you know what software and hardware to use. Post your dreams, and suggestions for how to make these reality.
I'd like to have my session (desktop, music, tv channel, etc) follow me around the house. I would prefer having a fingerprint reader next to a terminal in every room, but SunRay-style smartcards would also do the trick. I don't like the idea of wearing an RFID badge and moving the session automatically, I think that will cause conflicts. For example what if my loud music follows me into a room where someone is watching tv? Or my entering the room might even cause a switch of tv channel... not nice.
How would you build such a system? What components?
