I'm interested in working on this feature, with (hopefully) some guidance from emacs developers. If I wanted to start work on it: 1. Where should I begin? 2. Is it even do-able in terms of complexity, or will it touch the fabled and scary redisplay engine? What do people think? I've have some experience with C and elisp, but mostly an emacs user till date. Perhaps my chance to contribute back. regards -- aaditya
