@Hal: Enjoy them
It's a pity that one can't embed two or three fonts and then get "Publisher Font 1", "Publisher Font 2" and so forth as options.
Ah well. I've settled on "my" version DejaVu Serif some time ago, and my entire library is EPUB-based. I only convert to AZW3 to use on the Kindle, so it works perfectly to just embed DejaVu Serif E-Ink into the AZW3.
