Hi,
I have been researching Multi-Touch for the past year as a Hobbyist, and I
consider myself somewhat well versed in the technology:)
While that method would definately work, its obviously going to be cumbersom
and not portable at all. I have been experimenting with a method of
Multi-Touch that uses an array of Phototransistors, and I currently have a
8x8 Array working very well(3x3 Inch active sensing area, plenty to cover
the FreeRunner's screen). Its only issue is speed, which is going to be
fixed soon with my Digi-Key order that is on its way.
Mine obviously isn't perfect either, when I built it I had a more
Laptop/Tablet shaped device in mind(just because the array is ~1/4 inch
thick), but I do believe it will be easily adaptable.
Here is a link to my site where I have a video and explaination on an older
test I did:

And here is a picture of my newest version, 8x8 array:

In the near future I plan on somehow interfacing this to the freerunner. I
will probably have to separate the screen from the device, and place this
behind it(so I can interact with elements on the screen).
I'm very passionate about Multi-Touch, if you do get anything with a WiiMote
working, be sure to post a link+vid:) I'd love to see it.

Hi,
I have seen this video and due to a wide angle, a similar solution may
be adaptable:
