I was googling around for a free (and legally re-usable) text dictionary, and found this one with a very creative software license.

WordWeb free version may be used indefinitely only by people who take at most two commercial flights (not more than one return flight) in any 12 month period. People who fly more than this need to purchase the Pro version if they wish to continue to use it after a 30-day trial period.

Guess I’ll categorize this under both Technology and Travel.
