How about making Curio manageable through a source control system.

Like i've said before, Curio fits really well into my toolchain. It's usually the second thing I sketch on: right after I've done a sketch on a notepad, Curio helps me flesh out my ideas. Unfortunately, Curio is not at all friendly with most source control systems and that rules out parallel work between me and my workmates.

If Curio had an option to save it's files in a series of text files, we could merge parallel changes to projects. If we could do that, I could push Curio to my bosses as a tool to use for communication, and we would all be happy.

For bonus points, make the format something easily parseable such as JSON. Let us developers go to town. Open is always better than closed :).
