[fluid-dev] License question

[S. Christian Collins]

I have a licensing question about FluidSynth.  Let's say I'm creating a 
closed-source DAW, and I want to include a VSTi SoundFont synth based on 
FluidSynth.  If I create the VSTi synth as a separate, GPL-licensed 
plugin with available source code, can I sell the DAW software with the 
FluidSynth VSTi bundled?

I checked the GNU FAQ, which says the following:

> Q: Can I release a non-free program that's designed to load a 
> GPL-covered plug-in?
>
> A: It depends on how the program invokes its plug-ins. For instance, 
> if the program uses only simple fork and exec to invoke and 
> communicate with plug-ins, then the plug-ins are separate programs, so 
> the license of the plug-in makes no requirements about the main program.

> If the program dynamically links plug-ins, and they make function 
> calls to each other and share data structures, we believe they form a 
> single program, which must be treated as an extension of both the main 
> program and the plug-ins. In order to use the GPL-covered plug-ins, 
> the main program must be released under the GPL or a GPL-compatible 
> free software license, and that the terms of the GPL must be followed 
> when the main program is distributed for use with these plug-ins.

I believe this would cover my proposed scenario, but I want to be sure.

Thanks-in-advance,
