Almost forgot to mention, with the vncserver method having bvnc running in it's own server, the disadvantage is that while we have the stylus and the touchscreen, potentially connected bluetooth keyboard, virtual keyboard etc. usable on the second server, we can't use the keyboard and mouse used on the first X server. (our Desktop)

This can be resolved by the program x2x which can be found in most distributions. Using it is pretty straightforward. Let's assume you have the eReader right of your main screen in front of you, then you'd just type:

x2x -from <number of your primary server the keyboard/mouse is connected to> -to <number of the vncserver> -east <for right of>

then you can move the mouse cursor over the right corner of your screen and into the vnc session of the other device, or type into windows, as if it was a second screen. You will not be able to drag windows into the other screen though.

in my example this would be: (primary xserver is :0)

vncserver :1 (to start the vncserver)

then

x2x -from :0 -to :1 -east

as we are running a full fledged xserver, everything will work in that vnc session that works on our primary server, including game controllers and such. We don't need to care about any security for the created traffic as both severs run on the same PC, and there will logically also be no latency as the tablet has nothing to do with that traffic at all and basically only displays the results. Just a heads-up: this also works over a network. Also yes, you will see two mouse cursors on the vnc session as you'll have two mouse cursors. You can even make them look differently if you want.

EDIT: corrected left to right. Heh.
