thanks for posting the results of your survey, michael. i didn't know
about the NESS project, it looks (and sounds!) quite impressive.

I have ported the "lambda" project to OSX (it works on Linux also). lambda is a 2D FTDT simulator effective in room simulation acoustics but also very accurate in tube simulations. I have used it to simulate the Kempelen speach machine with nice results. It is by no means real-time, quite the opposite (as all the FTDT systems I know). 

Speaking of FDTD, I just came across the commercial synth Kaivo:

I haven't tried it, but the examples sounded quite nice.  I find most
of the FDTD stuff I've heard to be fantastic. Curious too that it's a
realtime plugin.
