It's not a 1:1 plugin system as you all will most likely want, but it does work!
Using a game wrapper for Mac called Wineskin, you can successfully wrap FL Studio 10.
FL Studio runs better than it ever did in Parallels, and it even loads VST's as you'd expect, and can render tracks right to your Mac desktop!
Once you use Wineskin to make a "FL Studio.app" you just need to "browse package contents" on the app, and copy the plugins into the VstPlugins folder you'll find inside.. pretty nice!
