What you want is Windows NT, which runs 16-bit (for want of a better
term) software in a virtual machine.  You can then write a device
driver to emulate the dongle which you need for a bit of software,
and you're away.

This is only easy to implement on dumb dongles - those which give
the same response every time to a given stimulus.  I can, however,
now use OrCAD without having the damn thing fall out of the back
of the machine on a daily basis..
