Your addition of e-book export really caught my eye. I've spent ages using various tools and coding .epub and .mobi by hand - (well, they are 'only' XML files in a .zip really) despite the claims by Pages/InDesign to export to one or both of these, the files created don't validate so are typically refused automatically by electronic distribution channels. Straight to .epub and .mobi from Scrivener is very, very interesting. I'll have to spend some time experimenting.
