Well, AU doesn't deal with GUIs at all, AFAIK. Porting it to Linux
should be doable, I guess, but I'm afraid the situation is rather
similar to that with VST; most plugins depend heavily on either
platform specific stuff, or proprietary technology for their GUIs.

Well, at least you don't have to sign an NDA to read it, but other
than that, it would be the usual copyright stuff, basically - but
IANAL.

I don't think we can prevent someone from creating binary compatible
hosts or plugins using their own headers instead of ours. As long as
we can't prove they just copied our work, and then extended and/or
changed it, we can't do anything about it, I think.

It's not that strange, really. We just do what we like best most of
the time, and that generally means hacking away on various little
projects that we find interesting. Whether they're useful or Yet
Another <whatever> is secondary to most hackers. And of course, "I
can do it much better!" (although no one would admit ever thinking
that ;-), and running your own project is more fun.

Yeah... The ones that are truly interested do *only* DSP hacking, and
the rest generally don't deal with audio at all. Besides, even if you
have other skills than hacking, hacking just takes too much of your
time. GUI design and graphics aren't things hackers in general spend
much time on, be there artistic potential or not.
