Open_Sailing is open source. Our principals are similar to WAVE - we want as many people as possible to be able to contribute to the system, and benefit from it. We've been looking at open source software (licensed under General Public License), Creative Commons and Copyleft.

Maybe we should investigate a similar stance to Google WAVE as a legal standpoint? (Plus, the 'WAVE" name ties in with Open_Sailing nicely, don't you think?!)
