When hard wiring smoke detectors in an older home, is it necessary to interconnect them? ...or is a smoke detector on each floor a big bonus compared to battery operated ones?

Around here most AHJ's let it slide, but it is really not an NEC issue rather a building code issue. I've often thought how nice it would be if FireEx, etc. would come up with smokes for the retrofit market that could be powered by different branch circuits and talk to each other VIA RF and be NFPA approved.
