Possible Multitouch Input/Pressure sensitivity

I know the 3DS is not multitouch compatible, but check this out. If you punch this small code in

@L
GCLS
TOUCH OUT TM,TX,TY
GPSET TX,TX,#WHITE
VSYNC 1
GOTO @L

and if you try and use two fingers on the screen, you should see the white point sit itself evenly between your two fingers. What's more, if you give one of the two fingers slightly less pressure, you should observe the point move more so towards the finger with more pressure, so I guess my idea here can serve as a means for pressure sensitivity. Perhaps some genius programmer can reap an awesome bit of code to accurately guess the location of the two fingers by monitoring the movements of the coordinates of the oscillating pixel. I've already played around with this enough, and I think it to be quite a challenge. I'd imagine the pixel would have to oscillate in order to make assumptions of the finger's locations. What do you think?

It would possibly work with two fingers, but it would instantly break when they put on another finger. Also, do you even know where your original stylus is? I lost it a few weeks after getting my first 3DS. lol

This would be nearly impossible, as you can easily replicate the actions of two fingers with one point. Whether or not you're using two fingers would be ambiguous. Also, move your fingers in and out toward the point. The movement is essentially equivalent.

Yes, but if you are not pressing down very hard, the point would oscillate between the two contact points. I'm not saying it could pinpoint the exact location of the fingers, but it could get the general area. A system could draw a line that the point seemingly follows and could assume location based on the average length of the line.
