hehe .. well I will further assume that whatever
you want to do is _legal_ in your country and I
will just do some brainstorming here which must not
be considered an advice or incitement to do something
illegal ...

depending on the number of guests which would
require such changes, and the way the check is
implemented, you could do one of the following:
- write a preload library/command wrapper to fake the MAC
- hack the kernel to report per guest MAC
- use dummy interfaces and assign a separate MAC
of course, IMHO you should _pay_ for the migration and/or
_complain_ to the company where you got those licenses
from ...
best,
