Operate a MN via a cold wallet?

[Voluntary]

Is it currently possible to operate any masternode (privately or hosted) without exposing the private key of the masternode address to an online computer?

If not, is it technically possible? Is there some signing operation that can be safely transferred between online and offline computers?

Currently no, but will be available in 12.1
