high voltage home runs?

["John O" <johno@#no^spam&heathkit.com>]

I'm reading a contribution to my project from an author who claims there are
lighting controller devices that require 120 VAC runs between the controller
and each controlled light circuit.

At a glance, this seems like a helluva lot of work, a crazy way to wire a
house, and outrageously expensive. Would such a system ever be built these
days? Did such systems ever exist?
