Thanks for the answers everyone!
I will play a bit more given your input.

webdm seems similar to what I had in mind, is the source code for it
available somewhere?
I'm in particular curious about the required security policies (I see it's
a framework, not an app) and interaction with the snappy CLI manager (if
that what it's using).
