After reading through
this thread, I believe one essential feature to add would be an automated export capability so that say your team has a VPS of some sort. When you get back to the hotel, you just type in a command or push a button and the entire database will be packed up and sent to the server. I can see how that won't be much more than some ZLib magic
Note that the link that's above is actually linked to my VPS. It provides many cloud features that are unbeatable, especially the fact that you can run any application that you want without asking the provider
