I guess you could do it...can't say it would have been tried already. Basically when you think of a VWM think of a really big desktop. So if you have a 4 wide desktop you should in theory be able to place things outside of your screen resolution and see them on other VWM's. Now this would only be a theory of how to get this done based on old ways of doing things. It may not work with current VWM modules.
