Nope. It doesn't work.
I wrote a simple "Reboot" channel a couple weeks ago that essentially crashes the system by loading too much information into memory:
viewtopic.php?f=28&t=32810&p=206136#p206136It's a hack, and has the same side effect of sending logs to Roku as the remote reboot sequence, but it's easier than unplugging and replugging.
