More than you might realize...

A platform port necessarily rewrites the architecture-specific parts of 
the operating system.   How much beyond that minimum gets reworked, 
rewritten and redesigned, varies.  Probably less than what should be, 
and more than what folks with existing kernel code would prefer.

But I don't see VSI moving to Mach.
