that's the way i read the 'apsl' too.

VST is also very, very 'tainted' as linus would put it; personally
i've decided to not even look at it. (ot: in a recent longish mail
conversation i had with info_AT_steinberg, they refused to give the spec
of the '.arr'-file format that is more than ten years old. so much
for steinborg's interpretation of 'live and let live' :).
i believe that with patience and prudence 'lad' may be capable of
producing an interface definition capable of connecting all our
audio/MIDI apps and libraries in style, without deriving from CA
or VST.
i think that Jack and its quick adoption shows the potential is
here, but i also think that o-o-p is a big performance burden in
most cases (otoh i seem to have a faible for aged hardware ;).

true. i like to see this as idealism shining through. otoh i think
that apple's policy of 'hiding gory detail from users/developers'
sent OS < X down the road to hell, and (again ot:) i think that if
they do not come to their senses in time, OSX will travel down that
road, too.

still, the API seems generic enough to hide whatever quirks may be
lurking beneath the shiny java spec.
