If I could extend this a bit further, it would also be great to allow rooms to be either password protected or limited to certain devices only. I have my whole family on roomie, but also use it at the office and it would be nice to prevent the kids from playing with my office controls or even the master bedroom for that matter.
Maybe an unlock toggle (so it doesn't need a password each time). The first time a device tries to enter a room that is protected, it asks for the password and can store it locally on the device. Going into edit mode would allow you to "re-lock" the room if you wanted to undo an unlock.
The problem is forgotten passwords. Extending the free guest app idea from another thread, if guest remotes could be setup, then you could simply set kids and guests in this mode and any room marked as "protected" would not be useable from these devices. No passwords required.
The problem with the guest app is potential piracy with profiles being built on a valid copy and used in multiple locations on guest apps. Suggestion would be to only allow propagation via wifi sync from a full copy and have profiles expire after some reasonable time frame.
Anyway, the basic idea is being able to protect settings and rooms from changes and usage respectively.
