#4 - Teachers can get a discount on Rhino too (Hell, I did), and it doesn't matter to the academic reseller if the software is part of any curriculum or not (though the folks who made Rhino was cool enough to send along a very nice curriculum breakdown of their product, enough so that teaching it as a side class wouldn't be a half-bad proposition.) #6 - Rhino's academic licensing allows for commercial use of Rhino, though not all proggies allow this (3DS Max ferinstance does not.) Therefore, this is not an ethical question as much as it is a legal question... if you use an academic copy of 3DS Max for commercial use, you've violated the licensing agreement, pure and simple. Discreet can revoke your license the moment you sell something made with the academic copy of 3DS Max. This is because you have to agree to those terms before buying the software. Zone alarm? Whazzat? I use Linux w/ iptables, portsentry, and a whole host of GPL proggies as a firewall. If I own a legal copy of any form of music (vinyl, CD, whatever), I can rip whatever I wish onto my hard drive; as long as I don't distribute the results, the RIAA can kiss my dufflebag for all I care. /P
