Sideways are an app developer that don't get the attention they deserve. I've just come across a demo video for a new piece of software they have available for license. It's called Buddy Reading. How would you like to use your iPad to read a story to someone even though they're in a different location. If Buddy Reading is integrated into the reading app, you can do it.
Sideways have a number of other clever products. I think they're worth a look.
Nate Hoffelder is the founder and editor of The Digital Reader:
"I've been into reading ebooks since forever, but I only got my first ereader in July 2007. Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."
