the license situation is never going to be clear until Steinberg clean
up their act. its more complex because libfst gets linked into your
application and your application requires the VST headers to be around
during compilation. my impression is that other solutions do not.

the problem is that there is no single answer. if you want to run 1 or
3 VSTi's then i would agree with chris' assessment (for now,
anyway). but you cannot use this model to put a VST EQ on 12 tracks
and a VST delay unit on 2 others and a VST looper on another. the
architecture doesn't scale. so you have to define the problem before
you can really way what the best answer is.

the way wine now handles threading makes this point mostly moot. wine
completely overrides the pthread "vfunc" table for any NPTL system and
even (i think) newer linuxthreads ones. you may think your app calls
pthread code, but if its linked using winemaker, its not (at least,
not directly) :) and of course, the new version of fst will require
winemaker compilation as well.
