The simultaneous idea sounds very similar to the idea Nigel had around a year
ago.  It may have been implemented to some degree.

The timeout feature could be done using the ACPI alarm interface, but there's
no reliable way of knowing how long the system can remain in a suspend state
on the x86 mobile platform, so waking up at the right time would be tricky if
not impossible.
