I'm evaluating 1Password for possible purchase. A critical feature for me is being able to access saved passwords from computers other than my desktop PC. All of the instructions for this sort of thing I have been able to locate are specific to DropBox. Since I already have several different cloud storage accounts including Box.net and Google Drive as well as cloud backup with SugaSync, I'm a bit hesitant to open a DropBox account just for this use. Are there any other ways to sync across machines that don't involve DropBox?
