If someone has funding, why this would happen sooner.

The unix VM is built from time to time by Ian Piumarta, the cocoa  
version is unix like with nods to mac support

I build the mac carbon version from time to time, which is mac like  
with nods to unix support.
This VM is based on the original code from Squeak Central out of Apple  
in the 1994-96 timeframe,
however much of it has changed and the os-7.5.5.-9.x support was  
dropped during the transition to MacIntel.

To transition to 64 bit, we need a pure cocoa version, all support  
routines need to be check for 64 bit issues, and all the plugins  
rebuilt, this is all outside of the issue
of having either the VM in 64bit mode and working with either a 32bit  
or 64bit image.

David T Lewis has been looking at the plugins.

Ian and I have been lately talking about the Cocoa implementation.

Lastly I'm not sure a headless os-x VM will run in 64bit mode, I don't  
know if anyone has attempted to compile it and confirmed all the  
support routines specific to os-x darwin
are working as expected.
