One of my clients uses such a system in his home. When he's away from
home he VPN connects to his home panel and uses a web browser to keep an
eye on things. He can control any light in the house (and probably
outlets too.)
    Granted, it's a more expensive. But it's also relatively common,
if the quantity of companies that service such home panels is any
indication. It looks like Eaton offers a guy that retro-fits into an
existing panel.

    Remote Controlled Circuit Breakers

    Eaton's Remote Controlled Circuit Breakers offer energy
    savings, convenience, and flexibility, all within the
    smallest breaker size in the industry. Schedule times for
    lighting or building systems to turn on and off. Easy to
    upgrade existing panelboards using remote-controllable
    breakers. Select from plug-on or bolt-on mountings in
    120/240V or 270/480V. For complex systems, see our
    complete line of Pow-R-Command Lighting and Load Control.
