I've downloaded the VST development kit from the Steinberg site, and
accepted the use conditions. Then I've built the fst package (as you
would compile any other VST plugin using the Steinberg development
kit) and uploaded it to non-free. From my understanding this is
perfectly legal, as is legal to distribute VST plugins compiled with
the VST SDK.

Mmmh, I'm not sure to get this point, please would you elaborate?

We could probably upload that too then.

I think so, but I'll let more knowledgeable people answer this.
