Curtis, I'm considering the same sort of thing (CTs on branch circuits) - I had planned to just expand on what Trystan had done, but possibly with an analog multiplexer to switch between, say, 16 inputs. The chip you mention sounds interesting but I guess you need one for every branch circuit?
Have you found a good source for the branch circuit CTs? We ordered some from CR Magnetics - they seem reasonably priced and as a bonus, they have spec sheets. ;) Will let you know how it goes.
