I'm not sure how much this would really buy them. I guese the idea here
is that there would be a chip in the speakers + reverse engineering
the algorithm would be tricky, if not impossible, if they made the
I guess if this chip also included the D/A conversion (as opposed to
pushing out the digital signal to a separate D/A converter) and spat
out an anlalogue stream only as good as the speakers need then
they might be on to something.

As I see it this sort of thing is ntothing but bad news for
open source systems.
Since it is open source people can get hold of the sound drivers and
put in hooks to dump out streams.
With windoze, source isn't usually available for the sound drivers,
so the risk of people hacking these and putting in hooks is much
So, I suspect folks like SMDI won't exactly be rushing to produce
apps to play their products on Linux :( -- but this just invites
linux users to reverse engineer their "property", if they won't
provide the apps then maybe they deserve what they get.
As I write this I'm beginning to think that the chip in the speakers
might actually be better for linux. SMDI et al, could release the
specs for driving the speakers without worrying about losing their
security. Linux would then be on a much more level playing field.
