Just a WIP of how I imagine service discovery could work with LibreMesh and Lime-App.

Hi Luandro!
I would suggest to rename the package to something more telling than just services.
Thanks!

Also, is Network > Services a new submenu?
I see only this package there.
Did you consider including this package in an already existing menu?
