I've started working on refactoring the redundancy and load balancing code in MV3D. This is definitely going to break some APIs and persisted data. I can go the extra step of adding in automatic (or manual) converters for the data if anyone has data stored in a MV3D datastore that they want to keep. However, I don't know that anyone does. So here's your chance. Unless I hear that this will negatively affect anyone, I'll be breaking the APIs and persisted data. I'll have to wipe the alpha server when I switch to this. Anyway, let me know now, or don't yell at me when things break.
Though let me say that this has not been an easy process, so it could take a while before it is ready. On the other hand, this is the last major breakage I have planned. Once this is in place, the API and datastore should be relatively stable. If they have to change, I should be able to provide a migration path. I already have a migration for some of the changes I've made, just doing that the rest will probably double the development time.
