Hi there,
I got an Idea for the cables from IC2. Pretty often you not only have to wire up electrics but redstone signals as well, making lots of wiring redundant. It would be great to combine the cables with redstone to make it carry EU as well as redstone signals.
For example powering a Tesla as well as toggling, controlling an reactor, toggling splitter cables straight from the MFE/MFSU ... applications are endless, and it would make designs far more elegant and compact.
