[pluggo] Pluggo as a VST to AU adapter for Logic?

Is it possible to use Pluggo to run arbitrary vst plugins in Logic, like the FXpansion adapter does? http://www.fxpansion.com/index.php?page=5

Max/MSP builds plug-ins as .vst files, so I tried dropping a .vst in /Library/Audio/Plug-Ins/VST/Pluggo and rescanning with the Pluggo component, but that doesn't work. I guess it makes sense that Pluggo only works with Max-built vst files.

I can build a Max patch plug-in that uses the vst~ object and get a vst running inside Pluggo in Logic. But in Logic I can't open the original vst's GUI like I can inside of Max (via a double click or open message to vst~). So it seems I'd have to build my own GUI around vst~ in Max.

To use the original plug-in's GUI, I should be able to host the vst in Max and have Max and Logic talk to each other with rewire. Is that the best option?
