I have a time management application that I use at home quite a lot and have running most of the time.

At home, I have a desktop PC and a couple of laptops scattered around the house...all networked together.

Unfortunately, the application I use is not multi-user and I risk losing/corrupting data if it has been left running on one computer inadvertently while I start using it on another one in another part of the house.

I use Live Mesh to automatically keep the application's database synced across the different computers and I just need some way of making sure that I don't start using the application on another computer before closing it down on the previous one.

Anyone know of any Windows software that can detect if an application is running simultaneously on different computers on my network, and warn me if I am about to have two open at the same time?
