Yep; where I work (small university dep't) one of the faculty members has it on all his desktops.
My main grumble about OpenSuSE is that, at least until 11.2 -- I'm still fuzzy on the details -- you couldn't actually do an upgrade from SuSE itself using zypper; you had to boot from the DVD and upgrade. I'm used to CentOS and Debian where this sort of thing isn't a mix of hope and prayer or a feature request.
I was at LISA '09, and Dr. Bruno Michel (works for IBM, mentioned in the article) made a presentation on this work (or at least very, very similar work). You can see the presentation, or download the MP3, here:

Interesting talk, and well worth your time.
