FreeNX suspend Wake on LAN question

I swapped a server in my closet from Windows 7 Pro to Ubuntu. On windows, I used remote desktop to get on this server. I would put it to sleep and then use WOL (wake on LAN) to bring the server back up. With FreeNX, when I suspend the server, it hangs the NX client up for waaaayyyyy too long and I'm forced to just sit and look at a frozen screen I can't get out of. Does anyone know of a better to solution for this problem? A command to force close FreeNX? A way to just force minimize the NX client? A remote, easy way to suspend the server? I've searched and can't find anything.

I know I can SSH into the server and suspend it from the command line, but it seems rather much to log out of the NX session, fire up SSH, log in and suspend the server. There has got to be a more elegant solution. I have even thought of scripting an SSH command, but nothing has just jumped out at me as The Way to go here.

It seems people have gone to a lot of trouble to make WOL work. I find it hard to believe that Sleep On LAN was never contemplated. Yeah, I understand putting other people's computer to sleep, haha, but a person would think someone would have written a snazzy client server gui that automates remote commands like this.

As a user of Mikrotik Routerboards, something scriptable similar to the gui Winbox, that would let you execute commands on a remote server would be neat. Does anyone know of anything like this?
