We're having a little problem with terminology. First, "VST samples" isn't precise - a VSTi plugin might *use* samples as sound sources, but as far as I know there's no VST sample format. Sampled sounds typically originate as a WAV or other high-quality soundfile format that gets wrapped into a sampler-specific format, e.g. GIG or DLS. A VST sampler plugin may well use GIG, DLS, or even WAV files directly.
Incidentally, I've read that the main developer of LinuxSampler uses the Vienna Symphonic Library. As I mentioned before, sample libraries are often usable as-is with the existing Linux samplers, provided the sample format is recognizable. So far the recognized formats seem to be GIG, SFZ, and WAV (possibly along with other formats supported by libsndfile). Btw, the Linux samplers I know of include Petri-foo, Specimen, Euphoria, and LinuxSampler.
The glaring omission in Linux-supported sample formats is the Kontakt format. I believe it has become the de facto standard for Windows-based samplers, thanks likely to the demise of Gigastudio.
