Box.net is a cloud-based file sharing service that I used extensively in my last book. Similar to dropbox.com, Box.net allowed my publishers and I to automate our workflow with regard to the publishing process, but more importantly, I was actually able to do much of the review and exchange of files from the iPad, which was really nice given that the book was on iOS. I’ve been working with a few companies over the past few weeks on coming up with various strategies for cloud interoperability, and Box.net has come up a few times in this regard. Looks like I’m not the only one!
