WHen compiling without USE_PIPES (as I did originally) we had loads of problems with 9x users due to the usage of socketpairs which don't work reliable on 9x systems. Additionally socketpairs are way slower than pipes. I'm using OpenSSH _as is_ for copying all my stuff from my windows box to any other box, including sources.redhat.com. I'm attempted to say, if rsync is the only application having that sort of problems, it's worth that if OpenSSH works for _most_ 9x users.
