While autoland is a real capability, it's got to be set up from onboard the airplane. It's not something that a manufacturer or the employer/owner-operator will perform from outside the aircraft.
An autoland approach is also sometimes referred to as a "Category III" approach, meaning it's got different visibility criteria than a regular "Category I" approach. One can literally land without being able to see a thing. The approach category describes the type of equipment required, the certification of the aircrew, the certification of the company, and the weather minimums for the approach. Autoland simply describes the ability of the airplane, and it's systems...two different things, but interrelated.
In order to make a successful auto landing, a number of factors must exist at just the right time. Multiple onboard autopilots are involved. An automated approach is a very closely monitored approach by the pilots flying the approach. If any factor fails to meet the necessary criteria during the approach, the airplane must be flown by hand, or a "missed approach" flown, or landed under different circumstances...an airplane may start out the approach as a full Cat III autoland approach, but may not end up that way due to a number of possibilities.
Long and the short of it is that the concept of an airplane simply approaching and landing on it's own without any internal input or oversight, given present aircraft and the present reality, is somewhat far fetched. Certainly an airplane could be programmed to do that (from onboard with today's technology and equipment), or even flown remotely if the equipment were available to do it. It would leave a lot of potential for error and disaster, however, which is why a living pilots sit in the airplane and operate the approach.
Even with a fully automated approach, the important distinction to recognize is that the pilot is still operating the approach. Whether the pilot does it by manually making inputs to the control stick or column, or does it through an autopilot or other controller...it's still a pilot operated approach. Just different equipment and different ways of accomplishing the same thing.
