It’s an interesting concept and a could see the value when you are in a hotel or another (away from home) location. It may also work on a platform without too much trouble.
You may wish to consider that bandwidth is limited on vessels though.
If a few people on the same vessel were to try and remotely control a PC at home (at the same time) it wouldn’t take long before the whole vessel internet/email system would slow down as the available bandwidth was reduced to a trickle as a result.
I would also suspect that if the IT guys on the beach (in any company) twigged on to this they would simply remotely block the protocol required to make it work. Initially that may seem to be no great loss at face value, but the protocol being blocked may be the same one as used for the likes of Messenger and Skype keyboard chat.. not so funny if they went also.
