Those are the old tools, you can expect a new set of tools once I get a chance to validate them against the Reader... in the last two days I suspect Sony tripled the installed base of BBeB capable viewing devices in the US, and that was just by shipping out review units.
Last time I checked you could still grab my BBeB formatted version off Doctorow's web site.
Now that the Reader does PDF natively I'm thinking HTMLDOC (
http://www.htmldoc.org) will be useful for formating Baen ebooks (
http://www.baen.com) for the Reader. But Baen content formatted with my tool will re-flow when you press the magnify button.
