Looking Good, Mike. You're making your way through that list pretty effectively.
I've taken another from my list as well.
1) Yes.
2) Yes.
3) No.
4) Yes.
5) No.
Although when I look at #3 and #5, I find they are mutually incompatible. If I were to rewire the house to accommodate the system, it would be a fairly big job involving a drywall ceiling in the basement and new electrical runs to the panel, ideally as part of a major remodel.
