I was actually saying that I'm interested in the general idea for Mac OS 9 (but not for OS X). While I would probably not do a formalized "challenge," I am casually experimenting with which tasks can be reasonably accomplished on a Mac OS 9 machine and which can't. People whose primary computing language uses the Roman alphabet can get away with offloading some of the more difficult to a shell server and using MacSSH. For non-Roman locales, using a legacy character encoding works for localized messages, but UTF-8 filenames cannot be easily read. MacSSH is open-source, though, so that could change!
