I'm sorry this is dragging on so long. It seems public domain is hard, both in the U.S. and in certain European jurisdictions. And people want a disclaimer. I did come across the MIT license, which may be close. <http://www.opensource.org/licenses/mit-license.php> Here is my non-expert attempt to adapt it, removing the condition, and changing "Software" to "Work": "Permission is hereby granted, free of charge, to any person obtaining this work (the "Work"), to deal in the Work without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Work, and to permit persons to whom the Work is furnished to do so.
