Something I prepared earlier for X3 (/Steam) ... and generic vs ProTools (which I have no experience with).
I've only tried with Tracktion 4 (DAW) which only seems to only handle 64bit VSTs but it's something like this.
Cakewalk SI Instruments work.
Cakewalk Sound Center should work (but is only 32bit - I can't test with Tracktion).
Most base level Cakewalk FX and Sonitus (Cakewalk) FX are actually DX not VST so you'll need a DAW or wrapper which can process Direct X FX/instruments.
Nomad Factory (Blue Tubes) and Overloud (TH2, Breverb) are restricted to Sonar (at the request/agrreement of the third party companies).
Celemony Melodyne Essential (from Studio edition) works.
XLN Addictive Drums at Producer edition is full product and completely usuable.
Other bits I've tried have worked.
