Exactly right.  Binary compatibility was an absolute requirement (because 
the idea of building a new compiler had already been discarded as too 
costly, and most of the compiler expertise had been laid off).  If LispOS 
are talking about creating a new VM and compiler for that VM, the design 
space is wide open.
