When I want to effectively isolate one music project from another, multiple user accounts should be the easy way to do it. It is except for one problem: software authorisation that is tied to the user account not just the machine.
When I try to authorise my POD software (for which a valid authorisation that I paid for exists on my TonePort), it informs my that I have reached the limit of authorisations.
This is silly.
Either use a hardware dongle or a challenge-response that authorises the machine once for all users, or offer a way for users to pass authorisations from one user account to another, on the same machine without intervention of an internet server.
However nice the POD software may be, if I cannot use it in a new user account without jumping through hoops, it is effectively useless and I am better off not using it at all, no matter how good the DSP is. Relying on a product for serious music projects where product authorisation issues may prevent me using it at a critical moment is not good enough.
Please put your paying licensed users first and make it easy for them to use your products that they have paid for.
