I am a big fan of TZ and own all of the Farsight tables. That being said, I think if they want people to donate $55,000 to the project, they shouldn't profit off this table.
They have families to feed, this is a business. Since the license fees are so much, they would never make this without people donating. After they pay off the fees, how else are they supposed to be paid for their time? The donations are not going to them.
Under your proposal, they would take the 55,000 and give it to the licensees. Work for a whole month to get the table scanned in and working, then turn all monies over to a charity. What about their mortgage, utilities, etc..., those bills don't go away.
