Tag a client to multiple screens

Question

Using Awesome Window Manager, I am trying to tag one client to multiple screens. I tried to use the following configuration in my rc.lua, but it does not work:

{ rule = { class = "<the class>" },
callback = function(c) c:tags({ tags[1][2], tags[2][2] }) end },

Am I missing something?

According to this link:

"[...] this is a limitation of how X works. A client, or "window", has a specific x/y position and a screen it is bound to."

So unfortunately, it is apparently not possible...
