Rhino requires documentation that you're either a teacher or a
student. I sent them a photocopy of my wife's teacher ID. That got me
an upgrade from v. 2 (which I owned and used at Wasino) to v. 4 for
$95.

Ah! See, Larry? It works!

I see that McNeel requires either a dated student ID or a
dated, current class schedule on the student side or an
dated faculty ID card or recent faculty/staff pay stub
on the instructor side. You could teach "Conservative
Underwater Basketweaving 101" and still qualify.
