I've decided to make the Shaw Alphabet the official script for Torei, just as a stylistic way to write things in English in images and have them appear 'alien'. I'm busy creating a set of templates so that you can just do {{tot}} to get a character image in your text.
I'd prefer to do this with unicode, but the font question is a bit difficult. If anyone has a quick way to get a shavian-capable webfont going I'd love to know.
