Vera Login Control

I suspect this one may be one for MCV.

I have created a second login account for my Vera. The intention is that when I am away my brother will use this account to monitor my house. When I return I would like the ability to simply disable that account. I would prefer not to have to keep changing passwords, a pain for me and my brother, but would like to simply use a virtual ‘Occupied’ switch that when switched to ‘Occupied’ would disable the second login, switch off simulated occupancy etc. and the reverse when set to ‘Unoccupied’.

Any ideas?
