I think this is a great idea.  At roughly $400 per target license, using
VxWorks is *way* less expensive than writing and maintaining the OS part of
"bare" hideos for a new processor.  Also, the change is certain to simplify
things for hideos users (I mean application developers).

If VxWorks-based hideos will, in fact, run on a 1MB MVME162, I'm in favor
of dropping "bare" hideos altogether.
