eGloo Technologies has posted a chapter from Managing Writers to demonstrate the capabilities of its tekReader publishing platform. You can view the sample chapter in tekReader here: Measurement and Metrics.
Thanks to David Coules and Don Stolee of eGloo for putting together this demo. We met at LavaCon, sent them the files a few days later, and they had the demo working within a day. They also nicely captured our print style, while keeping the book readable online.
