If you can generate an epub file, please consider distributing it via fifobooks.com (my startup).

We can make it available for non-epub devices like the Kindle and Blackberry, as well as the iPad, Nook, sony Reader, Android, etc.

You can continue to give it away free, or a charge a fee for it, and we're accessible from any country.

I tried exporting to epub to read it on an iPad. Both Calibre (calibre-ebook.com) and www.epub2go.com stripped almost all layout information, making the result unattractive and very hard to read.

I ended up buying GoodReader for iPad (0.99c) so I could read the magazine in the form it was intended to look on paper. Recommended.
