Interactive white boards and Fedora Xorg setup

I regularly use (a variety of) interactive white boards and the single
biggest frustration is getting the pointer device working so it's
actually useable.

Let me give you an example.

I plug and IWB into my laptop and Fedora configures is as an extension
to my desktop.  This is great because I can drag what I want to appear
on the IWB and not have to reveal my entire desktop.

The pointer device in the IWB works and I can use it as a mouse, but
it's rendered unusable because the mouse acts across the entire desktop
(both my laptop screen and the IWB).

Unlike a mouse, these pointer devices move the mouse pointer to where
you touch the screen.  For example, if the IWB is to the right of my
laptop screen and I touch the right edge of the screen then the mouse
pointer appears on the right side of my laptop screen, and not where
I've touched the screen.

The pointer device included with the IWB needs to be able to be
configured to do two things:

1.  Only work as a device for the IWB screen.  The mouse shouldn't be
able to be moved off the screen, only around it.
2.  Calibrate the pointer so that you can declare the
top/bottom/left/right of the screen (as where the image falls on the
pointer device isn't usually at the extremes of the device.)

Is this possible?

Does this make sense?

Is this something that's included in f13 (if it is I can't find it) or
could it be included as a part of f14.  As far as I'm concerned this is
a huge feature as I'm constantly finding IWB pointer devices are useless
unless I mirror (and mirroring reveals my desktop and usually squashes
the icons as the laptop screen has to be sized down and then I have to
move the icons back).
