Something similar to a storage monitor but for FE in the network. For the monitor wall nerds like me.

You can already do this with the ME Throughput Monitor. Double right click with any powered item on it and it will show the flux.

I wonder whether Matiam0 meant something that can be used externally, like generating a redstone signal based on fill level or for interfacing with ComputerCraft or such to populate their panels. It would be really cool to be able to pull storage data from Applied Flux and throw that to other systems.
