You still have the back feed issue. Sooner or later, someone is going to have to do maintenance on that new grid you just created.

Disconnect the grid on both ends of the issue, fix it, then reconnect?

The problem is that utility company distribution system operators can issue clearances (ensuring a de-energized state) on their systems disconnects, but not on individual home system disconnects. Its not a tough problem to work around though, all the troublemen would have to do is to ensure the line is dead before installing their shorts and grounds, if the line wasn't dead, they'd stop work and figure out which network was backfeeding the line they were trying to work on.

Sorry for the late reply.

Since it is completely distributed, you would need to have an ability to disconnect it pretty much everywhere, and as such could disconnect it locally. Eg. if a new house is being connected, disconnect the adjacent houses, install it, then reconnect (assuming a linear grid between the three houses).

Ah, thanks for the reply. I misunderstood your original comment. I thought you were talking about interfacing with existing utility company distribution networks instead of being completely distributed.
