you are not allowed to redistribute the headers. i suspect that the files that come with audacity (for example) are a violation of the license agreement regarding VST. likewise for kjetil's cool VST-with-wine system. BTW, i really must release the "jackvst" client, which allows you to run many VST plugins as standalone JACK clients. they have to have their own GUI, and they mustn't try to mess with windows at a deep level. i've tried about 8 that had GUIs, and only 1 of them failed. --p
