Things to do:
 - Move from QT3 to QT4
 - Build a ADC protocol library
 - Migrate from QT to wxWidgets

OS X specific:
 - place OS X Makefile variables in correct location in Makefile.am
 - have 'make install-osx' (and sub targets) only work when building the native version (ie, only if --enable-mac is set).  The Mac X11 version works like any other Unix build/install.  This step is not as critical as the other OS X points, but useful.
