ive noticed a few people wanted this, so compiled it
this is version 3.0, pre8 so very new
i use it as a daemon on iLiad
create an empty rsyncd.conf in /etc
cp rsync to /usr/bin
run with rsync --daemon
if you want to use it as a client you will need to have either ssh or rsh on iliad
(oh, i think as a daemon its probably going to need dropbear sshd installed and running?!)
enjoy
