A survey has found about one in five people would be willing to have a consultation with their doctor over the internet, rather than in person.
Obviously, video consultation couldn't fully replace in-person consultations with a doctor.
While you can do a lot of things over the internet, it isn't currently possible to remotely listen to someone's lungs, for instance, or take their blood pressure.
But there may still be a lot of advantages to a remote consultation.
For rural patients who may have a long way to travel to reach their nearest doctor, and may therefore put off an appointment until the problem is urgent, a web-consultation may be a good option.
