Found this entry by A. Burt (remember the whole sfwa vs scribd thing) and Mr. Burt seems to actually be a big drm-free e-book lover to various people surprise
Also Mr. Stross says the following in the comments:
"Also: in talks with the four major publishers I deal with, three have plans to abandon DRM within the next year, and are considering adopting pricing policies that will break with existing practice (i.e. minimum ebook price of 80% of non-discounted price of most expensive current paper edition) which should drive uptake."
