Apologize if my drawings are little too sophisticated, let me please elaborate the idea from real products.
A similar approach that has recently raised is the Samsung Dex where from a cellphone touch screen you can control a desktop. Like such.
However a more advance used that would make the experience more powerful would be using a real desktop initiative like the alliance with Citrix.
Said this, the modular system of touchpads screens and keyboards I thought could be a future version however a simple idea of this is used by Dex and Citrix with virtualized apps that, as far as I am concern would be inflicting the patent.
My enhancement is to work out the interfaces to control such applications and customize them in different screens. I think that there will be a time when XCP and Xenserver will ultimately include touchpards and virtual keyboards as a way of naturally control the virtualized apps with more natural language like gestures.
Thanks for reading,
