While there's still some confusion how to properly generate PDF content for the iRex iLiad, MobileRead reader vvv came up with a promising-looking frontend utility called BookDesigner (http://www.bookdesigner.org/wordpress/) that seems to utilize the open-source tool PDFCreator to transform content to PDF for the iLiad (and other e-book devices for that matter).

If you look at the screenshot (http://www.mobileread.com/forums/showthread.php?p=37284#post37284) of BookDesigner in action, you'll notice that there are all kinds of useful parameters you can adjust to optimize the PDF output. According to vvv, it still needs some testing; but who knows, if you try to be nice to him, perhaps he'll hand out a copy to you.

I actually downloaded and installed the 4.0 version of the program from vvv a couple of days ago (saw it mentioned in a thread here); it looks like a nice program, but I'm not sure he's released the version that supports the iliad yet; I couldn't find any way to save PDFs at all, actually. Anyway, if anyone else had a different experience please post, 'cause I think this prog has serious potential to be useful.

The iLiad version of book designer is still in development. It has not been released yet. But vvv said it will be within the next two weeks, so be patient :)
