Request: Ability to send Wakeup Packet to Client

[ga2k]

How hard would it be to implement the sending of a TCP/IP Wakeup Packet to a client so that we can use Barrier to login to a sleeping PC?

Ideally such a packet could be sent when the mouse tries to enter the client's activity area. Check if the client responds to a ping. If the client doesn't respond, send the wakeup packet and a message to the active screen saying "Waking up client - try again in a bit..."

This would have to be optional, of course, with a configuration option to enable/disable it.

Enhancements:

Maybe have a timer on the message with an option to cancel it, if the user was just waving the mouse around and didn't mean to go into the client's activation area. The message box say something like

 ------------------------------------------------------
|                 Mac Mini is asleep.                 |
|                                                     |
|   We will try to wake up the client in 10 seconds   |
|         or you can click "Don't Switch".            |
|                                                     |
|    ------------                    --------------   |
|   | Do it now! |                  | Don't switch |  | 
|    ------------                    --------------   |
-------------------------------------------------------

Then if the timer expires, send the wakeup packet, wait for the client to wake up, and perform the switch.

What do you think?
