@newscribe: Why do you not offer the book to Toni Weisskopf (Head of Baen Publishing)?
If you still owns all the rights on it (including the electronic publishing ones) and if it fits in Baen's profile - you could sell the book via
www.webscription.net.
And the publishing would be in 5 different drm-free formats (rocket, mobi, lit, rtf and html), so anyone with an ebook-device could download the one, that fits him most.
Best way to contact Toni - via the "Toni's Table" conference at
Baens Bar
