Do you think a valid project would be to debug pd / pd-extended 64 bit builds? After losing a few days trying to get a solid 64 build of pd+externals, I'm a bit disappointed at the current state. It's something rather boring, but would be quite useful for the future ... the next OSX (Snow Leaopard), for instance will be natively 64bit. (I assume for asking the question, I would need to be the mentor?)
