I would assume that re-writing the toolbox to a native processor is
much faster than simply emulating the original toolbox code.  But ARDI
might be able to supplement a totally based MacOS--i.e. slowly replace
certain function calls with native equivalents while simply emulating
the rest for compatabilities sake.
