Hi, I'm a Houston technical writer and contributor to Teleread.
I'm currently investigating how one could dump TEI stuff into epub for
a fiction manuscript.
(I noticed that the docbook people have a branch to convert Docbook to
epub

I find that epub imposes lots of limitations on navigation. We still
haven't gotten too far away from the linear model.
I haven't done too much stuff in .epub but I expect to be doing a lot
over the next few months.
