Yodeck has proved to be a great solution for us. We have been using it in yachts with a 3G dongle. The Raspberry Pi is very reliable (haven't had any issues so far) and easy to setup (actually no setup needed for us as they sent us for free all the devices preconfigured when we subscribed for a year). The support at Yodeck usually responds promptly to our request which are very few in reality since the solution is quite stable. Keep up the good work Yodeck and congrats to customer support - they are great!
