SignWriting looks like the best system as far as intelligibility goes, but isn't it copyrighted? I mean, I know that the creator has made it free for use and all (see http://signwriting.org/about/questions/quest0004.html ), but doesn't that still make it ineligible for use in a Wikimedia project? It would be like using a special copyrighted ortography for English, or a copyrighted conlang (Toki Pona, anyone?). Yet another issue that must be addressed, I suppose. Cheers,
