Thanks John.

So direct execution of some standalone Itanium VMS user-mode executables
might be possible with enough effort, but no running Itanium VMS as an
entity in its own right.

It really does speak to how complex the Itanium architecture is that
nobody has ever done an Itanium full-system emulator. :-)
