There is another use for the RaspberryPi that I have found. I use an SDR here (Software defined radio) and the Pi is perfect for running the control software for network connections to the device. The software (available on all platforms) is called AirSpy. The pi is perfect for projects like this. As a ham radio operator, I am b basically into any technology that can be controlled or utilized by open source software. Also, if you have some additional parts, the Pi can be used as a 3D printer controller. I also have a project in mind for converting live stream video into soundscapes (see the project seeing with sound for further info). This last project is not network specific except when the app for seeing with sound is running (it is browser based and requires a network connection).
Anyway, those are some other uses.
