eText, eText, where fore art thou, eText?

I'm sorry to say it, but, online Calculus texts are just not ready for prime time! My school just purchased the latest edition of our favorite text with the understanding that my students would get etexts and the other classes would get hardcovers. Just look at my beat-up text pictured above (c) 1995 and you'll see why it was time to get a new book! So, I get the etext and it turns out that its only for one user and has to be reregistered each year??? This is outrageously expensive! I don't get the problem. I also teach Computer Science and have been using etexts for those classes for several years now without a problem. 

For my Computing classes, we simply bought a class set of each text and got a pdf version for free! Now, I just upload one chapter at a time to http://www.edmodo.com. That's all I'm asking for. The eText can easily be identical in content to the printed book as most authors and publishers generate pdfs now-a-days anyway! I don't need any extra digital content, I can create my own. If you want extra digital content, more power to you, but it will take longer to create the books and these books will be far from free.

Here's the books I use in my Scientific Computing track:

1) Computer Math (Discrete Mathematics and Python):
