There's a clean-room reimplementation that LMMS ships with called VeSTige. Ardour3 also uses said code for VST hosting.
The effort isn't complete (they didn't re-implement all the corners), but it works well enough.
Ah, thanks for the info, must check it out.

I'm not aware of any licensing issues, but VST support is certainly turned on by default, at least at this point in time.
I tried building it with VST support once, not exactly seamless - not sure I ever got it to work.
