When ever a wire/frame wire(only tried those 2 atm) is removed near other multiparts, it'll disconnect u from server with a chance of crashing it. i discovered this when rewiring the redstone control for my treefarm because i used the wrong cable in the first place. This occurs in the latest stable build incase your wondering and it only seems to happens on a server.

So when trying to come up with a workaround, MFR rednet cables were the only other choice and if there is atleast 2 places along the cable set to a particular colour & one end connects to redalloy wire, the signal is held high regardless of the input.
