What about an Import/Export feature. For example, if you have a character (that's yours, or you're the GM) that you want to back up, move to another RPG, etc, you would simply press the Export button, and all information relevant to that character is saved onto your hard drive in an XML/text/whathaveyou file. Then you'd simply go to the appropriate RPG (the same one if you lost data for some reason, or another RPG you want the character to be in), and press the Import feature. Though the Import Character feature might be better as a GM only feature, or toggleable, to prevent abuse. No idea how easy that would be to code.
