A good exercise in futility is trying to enable Vino remotely and attach it to your locally logged-in session. There's basically no documentation for this stupid program and even when I could get it running (on the wrong display) it had caused dozens of brand new SELinux violation alerts. I have no idea why this is the default VNC server in Fedora.

So, note to future John, save yourself the headache and do this instead:

[john@home]$ x11vnc -display :0 -usepw &

It will even terminate itself automagically once I disconnect. That can be remedied by adding the '-forever' flag if I plan to disconnect/reconnect several times over the day.
