However, I think at the very least a name change from 'OpenPCR' would be
called for :-)  And you would have to _tell_ people that they can't use
it for PCR, thus removing the point of the exercise.  If the goal is to
produce very cheap cyclers for schools, etc, it would be terribly unkind
to let them violate the PCR patents without making it very clear to them
that is what using the machine for PCR would mean.  I doubt many schools
wouild want to take legal risks like that.
