Interesting. I'm living in Argentina - where the Internet connectivity is particularly slow. Therefore, my preferred setup is: everything local but backed up near-instantaneously onto the cloud. (I heart Dropbox.) Does anyone else have this problem? Are there other Dropbox-like cloud services to use for those of us with slow Internet?
I'm in South Africa, and have 10mbps but the latency to the States is about 270ms. It may be an advantage when developing though, because it keeps latency front and center. I'm working on a multi-player organizer that keeps everything local and syncs asynchronously with the server. You can use it for email and documents. Ready soon at https://ronomon.com.
