Hmm ... I like the command line client and am using that. Just a small tweak to be done on a linux system that doesn't use the rc.runlevelnumber directories. Instead of using install.sh, copy the sifyd and sifyconnect files to /usr/bin and add a line to your startup script (like rc.local) which brings up sifyd each time the system starts.It works perfectly on my slackware 10.0 🙂
