I'll note Ian has been working on a port of the VM code to Cocoa. The  
cocoa part is just the UI part of the Unix port, a bit of plug and play.

Once he releases it we'll refine it a bit, IE I doubt he even considers  
mac alias file/folder resolving as an issue that the unix folks are  
concerned about.

That most likely will become the basis of the os-x squeak port, just  
another variant of unix, with some really odd bits.
