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?).
He seems to say in that link that he *doesn't* claim any ownership of the writing system itself. In any case, the free to use for anybody sort of license is basically like the "BSD-style" licenses (or cc-by without -sa), which is compatible with both the GFDL and the general free-content philosophy.
