While Eric's still in the South Pacific, we'll point out that his latest column in the just-relased first issue of Jim Baen's Universe second year is about the relationship between drm-free ebooks and the opacity of the book market.

In this essay, I want to turn the problem around and approach it from a positive standpoint, by examining the many ways in which a non-DRM approach to electronic publishing can help the situation of authors and publishers."
