ANYPLACE CONTROL

Is it possible to add a put remote PC to sleep rather then shutdown etc function to the Power Management.

We can develop such feature which allows you to put remote PC into sleep mode.
but you will not be able to wake up remote PC from sleep mode via Internet connection.
Although you will be able to wake up PC via LAN, but in is impossible via Internet.

Do you mean that you want to sleep/wake up PC in the range of LAN only?
