I'm surprised the more logical combination of adding a "Print with Lulu" button to iPaper hasn't been added with commission for each sale going to Scribd (and possibly, in the future, the original author of the document so the platform could be used for previewing books from small-time authors).

The ability to instantly get a PDF printed and mailed to you via paper would be a nice feature.

Lulu on an merger spree ? I hear some more rumors.
