There's a paper (PDF) here:
http://www.media.mit.edu/resenv/pubs/papers/2002-06-IEEE-Sensors-Tapper.pdf
which describes using four transducers in the corners of a shop window
to detect
the location of finger taps on the surface of the window. Some of it
might be
relevant.
Also... hmmm. Could also be relevant to a cheap DIY drum pad.
