(Not completely a programming thing, hence not on SO, but more system related so thought SF could help, sorry if I'm missing a better place)
We've recently started a Maker/Hackerspace in Northern Ireland, and we want to put together an extendible system for rolling out information screens across the space, ideally with a script-driven interface to what is displayed on different screens in different areas of the space at different times.
Things like Network Statistics from our RFlow service, or Occupancy statistics from our Auth-server, or VM-performance statistics, or just tweets about the space or the IRC channel.
The machines that would run the screens would be fairly isolated and low power, we're thinking Raspberry Pis (if we can get our hands on a number of them) or some old EEE-PCs.
FOSS heavily preferred
