May not help - but then it may point your thoughts the right way -
Dedicated Hosting services have been known to provide remote access
(either web or telnet access) to the UPS powering your server allowing a
power cycle as needed. Combined with a remote console access (think
second pc with serial port connection to the server in question)
allowing single user booting to swap kernels from across the globe.
X10 home automation anyone??
