That is indeed true. I didn't have high hopes when first posting here, 
but since then I received plenty of insightful information. Thanks so 
far to all discussion participants!

I used the following: http://paste.ubuntu.com/1408532/

Observe the last line: "Max number of touches: 5"

Could you, if it doesn't take too much time, elaborate on how realistic 
you think an (optional) option is, to map the "fake" touches to x/y 
values of the touches we can really track?

For example I see that the latest head of easystroke (a gesture 
recognizer) started implementing multitouch support. So if I can record 
gestures with these additional fake touches I can at least use the 
additional fingers for easy/basic 3-5 finger gestures. I don't think it 
would matter then if two fingers are directly above each other.

Maybe I'm getting this all wrong though. How do you receive information 
about the number of fingers in the driver? Would you calculate them by 
"guessing" from the bounding box of the touch, or can you read the 
number directly from the hardware?
