We really need to do some survey and market research, but to kick off a
straw poll, having access to this sort of rig would tempt me to try playing
with the digital birds. :-)  ANd the whole idea of software defined radios
is rather neat, and suits my style of operation (fewer and more flexible
boxes - the logical extension of my computer based digital modes).

I believe the open source model has a lot to offer such a project, and the
use of open source software (and "open hardware", which may one day be also
commercially produced) could enable amateurs to take a lead in this area.

Well, I'm not a programmer, so my initial contribution would be limited to
configuration and testing.  However, I suspect there are likely to be lots
of software tweakable parameters and a who new art of radio to learn, so I
could possibly contribute as the project matures in configuration and
support, and perhaps documentation.
