In Feb 2005 I described on MMD a similar setup to the one that
Bob Meyer is now using.  It, however, uses Wifi and not Bluetooth.
It still works very well.  There is a new "Wireless DJ Music System"
from Logitech on the market which I believe will do the same thing
but much cheaper.  I have also lashed together a system where the
MIDI output from the computer operates an X10 remote and thus turns
on the piano.  Spencer Chase had something similar a few years ago.
