This is going to be an opportunity for the community. :-)
I have some plans in this area, but I couldn't guess how to best fit into other people's workflows.
What might be nice is if there was a way to sync a git repository with Riak, and then Nirvana could just pull the relevant code from that. Seems like it would be the best solution, but looking into that- from looking at possibly integrating with a github API (do they have one?) to command line scripts is something I'm punting on to focus on the essentials.
Again, essentially what we do in concept. The dev side is a separate db (git could represent this), and once something is published past dev the record is copied to the production db (Riak in your case). The dbs have in-memory local machine cached versions, for speed, but also for reliability. You don't want your N machines depending on one db point of failure, so the local cached copies exist to mitigate that. (They receive updates via a multicast mechanism.)

But I do agree with your points!
