We work with projects creating a suscription for each project. That way we can have control of how much money we expend on the windows azure service.
But sometimes, we would like to reuse existing machines that we used in one suscription to a second suscription for a different project.

I know we can replicate VM, o use backup disk, etc, but it would be so much easier if we have an option to just move one VM from one suscription to another suscription. It seems very easy and is only for accounting issues.
