Hi What I'm after is an application I can install on both my Macbook and my iMac. If I were to make a document on my iMac, it would automatically upload in the background to a 'cloud' server. If I were to open my Macbook (say, at University to do some work), it would automatically sync the documents from the cloud back to the computer, and changes would be uploaded again. Preferably something that integrates really well with Finder. I think MobileMe is sort of what I want but it's too expensive for me. Any such software exist?
