I'm searching for creative -- or at least non-standard -- uses for Version Control. I have a specific purpose in mind, but I don't want to stifle your creative thoughts with any sort of limitations.
To that end, don't eliminate a creative use of VCS dealing with source code just because I said creative/non-standard: That doesn't mean it can't deal with source. It just means I'm looking for ideas other than branching, merging, tagging, rollback, and forking.
For example: I would consider the use of Version Control as a quick & dirty SharePoint knock-off as a passable answer, but just barely.
What other interesting uses have you seen?
