Jim it's a bit more complicated, you see the VM needs only to be  
compiled when a change in
the image or to the VM code itself requires an update. Thus you could  
have a VM that is hundreds of
patch numbers older than the image because none of the image changes  
force a VM change.

  Also there is some loose attempt to ensure  newer and older VM's will  
run older or newer images,
usually across version boundaries

I think the VM maintainers would welcome someone with quite a few days  
of idle time and a
windows, mac and linux machine to construct a matrix of which released  
image version works
with which VM version.

  For the macintosh VM, newer VMs are significantly faster and lots of  
bug fixes than a 3.0 VM,
yet someone using a 3.0 image is unclear on the fact he could migrate  
to a 3.4 VM .

What's not clear is the risk of doing that, certainly I've tried to  
enable such a migration, but no
"formal" documentation/statement exists.

PS any known macintosh VM/image version issues should be emailed to me.
