Supporting the Free Software Foundation's day against DRM

The O'Reilly Media, the publisher of my ebook Virtualization: A Manager's Guide, is taking part in the Free Software Foundation's day against DRM. I thought you might like to know about what they're doing.
Here's what they have to say about it:
In Celebration of *Day Against DRM* Save 50% on ALL Ebooks & Videos
Having the ability to download files at your convenience, store them on all your devices, or share them with a friend or colleague as you would a print book, is liberating, and is how it should be. If you haven't tried a DRM-free ebook of video, we encourage you to do so now. And if you're already a fan, take advantage of our sale and add to your library.
For one day only, you can save 50% on all O'Reilly, No Starch, and Rocky Nook ebooks and videos. Use code: DRMFREE
Ebooks from oreilly.com are DRM-free. You get free lifetime access, multiple file formats, free updates. Deal expires May 4, 2012 at 11:59pm PT and cannot be combined with other offers.
I've always thought it odd that it was fine for me to loan or give a book to a friend, but doing the same thing, with the same content in the form of an eBook was not allowed. I'm happy to see that FSF is saying something about this topic.
