Thats the idea yes! you can run dotmesh on your own servers and install locally on each users machine to then push and pull just like git remotes. It's using copy-on-write so you are only pushing the difference. Another main use case is for CI to consume volumes, run tests then snapshot the results.

We have a hosted service if you don't want to run your own nodes (https://dothub.com) but the server and client are both open source. disclaimer: I work on the project
