Kitsune provides useful abstractions for modifying your program for runtime updating and tools for automating state transformation between versions of your program.

It would be entirely reasonable to implement DSU all within an app's own codebase, particularly until there's a production-ready library/tool-set. The downside would be that you'd probably end up re-implementing a lot of what Kitsune provides.

For our purposes (evaluating Kitsune-style updating on a variety of server programs), it made sense that we'd want to have a common toolset that we applied to all of the programs.
