Yes, I've been added to Planet GNOME!
Well, not much else to say, as I blogged recently on my work.
Just a small gift:
You want to try this? Grab the slave-connection branch from git://github.com/gcampax/gdm.git and the screen-shield branch from git://github.com/gcampax/gnome-shell.git .
Note: you need to have the latest gdm running, which means probably turning it into a rpm. And that will completely break your greeter, so make sure you have autologin enabled.
Also note: I follow the "Rebase early, rebase often" policy, which means that following my personal repository is a very bad idea. For "stable" stuff, you can usually find a wip/* branch at the corresponding gnome.org repo.
