First question: must you use an rsync daemon on the Unix side? Rsh or Ssh is a lot easier. If you do need to use it, you need to know that the original intention of rsync modules was to only permit files under that module to be accessible. With the default "use chroot = yes" option, rsync chroot's to the directory so no files outside of the top path can be reached. Long ago I added the "use chroot = no" option so an rsync daemon could be run under a non-root user id (because only root can run chroot()), but even then it goes through pains to filter out paths that attempt to go outside of the top module. However, I believe, but am not sure, that if --copy-links is used with "use chroot = no" it should pull in files pointed to by symlinks from outside the top. Try it out.
