I had been wondering where Beeper's route to profitability was, but if they can get Continuity and AirDrop stuff working with Windows that will be an instant no-brainer subscription for a lot of people (including me), so I guess it works out.
It works over wifi, but you might be interested in KDE Connect [1]. It can do clipboard, remote input, file sending, command running, etc. on Windows and Linux.
