Build your own net.
Remember the internet from the ITCrowd? You could build sort of your own version with the RPi-A: You can build your own in"tra"net versus using the in"ter"net. But if you really want to be useful you might want to use a stationary satellite. But then to get world wide coverage you might need several stationary satellites. Do not tell me someone has not already done this. So you get: Getting close to home. Even if you do not have all that fancy equipment you can still build a private intranet. A bit dated, but still viable: In part one you will get the basic setup and a few tweaks. http://www.instructables.com/id/Your-personal-intranet-Part-1/ In part two you will get some additional tweaks. http://www.instructables.com/id/Your-personal-intranet-Part-2/ Have fun.
