Create a Roku screensaver (see the clock example
), then have it use the ECP launch function
to start the channel as soon as it starts up. Have the channel prevent the screensaver from kicking back in
if you're not playing video continuously, so it doesn't end up relaunching every 5 minutes (or whenever the screensaver is set to kick in at).
Obviously, this won't allow you to idle on the home screen or in most other channels, so you probably wouldn't want to distribute this widely. But if it's for some custom one-off application, it might be useful.
