Is it possible for DS' touchscreen to detect two 'touches' at a time? I'm just curious, sorry :)

i dont think so.
If you do this in Pictochat or in homebrew paint software, you will get a line instead of getting 2 points!

If the touchpad registers more than one point (which it normaly does, because your finger is too big ;-) it calculates the middle between all points and this point will be returned. This is done in hardware, so you can't read all points touched. Try in PicoChat to touch 2 small points (with 2 stylus) and move them both in one direction, you should get a line between these points (as if you would touch it in the middle between the 2 stylus).

You could interprete a very sudden move as a second touch. You can then calculate the second point by using the first point and the new averaged point. It probably won't be very accurate. Perhaps even three points will work.

seems like to me it's working like a pc laptop touchpad if so....

I was just curious if it's possible to make a simple "Piano Tech Demo" by using multiple styluses (or fingers). After DF's and juhees' post I'm pretty sure it'd be damn hard to code it.

Indeed. However, the microphone could be put to some affect if you were prepared to implement some voice recognition for notes, so the user could tap one note, say a C, and say "A" for an A. Obviously if you wanted flats and stuff you'd need to think of other words, and this isn't a very usable solution, but it would do the job.

if your after chords in your demo, you could try something similar to "Casio Chord" that you get on their electric keyboards...although i think a sequencer would be better than trying to play music in real-time

Now here's would be useful on the DS: an S3M editor.

Also, it would only work for taps, if you move a stylus after that, you can calculate only relative movement...
