My dream application would be to have the treo display "phonocardiograms" from the new generation of noise canceling, electronically recording stethescopes (http://products3.3m.com/catalog/uk/e...er/output_html)

With this stethescope, one can graphically display the heart sound on a PC. The native software allows for beaming the file from the stethescope to a Palm device. I would expect that it would be relativley straightforward to have an app on the Treo that would dispaly the phonocardiogram, instead of having to first transfer it to the PC. This would be a wonderful teaching application, and I would pay good money for it.
