My concern is that it might be difficult to "tune" Cpuidle to
distinguish between "non-essential" processing (which could tolerate
suspending) versus background activity whose completion the user is
nevertheless awaiting (and which should preferably avoid suspending).
I use ethernet rather than wireless. Historically, my systems have
suspended despite an ongoing (via ethernet) data transfer -- that's why
at home (when my XOs are plugged in to AC) I disable suspend. I am
doubtful whether Cpuidle would consider the small amount of CPU
processing involved with handling ethernet packet interrupts as
exceeding whatever "idle threshold" it has been designed to recognize.
