Ability to save stories in other formats (other than PDF) for eReaders?

This was asked before but with all the other new additions/improvements to MSV may have fallen to the wayside.

While PDF is pretty much the standard for story portability, it's not very e-Reader and e-Ink friendly-- at least, not on a Kindle.

EPub, DOC, .mobi, Rich Text Format... Even adding a HTML option would be great.
