So, it would need to be adaptive and "intelligent" in its navigation, or it would have to be monitored and remotely piloted by a crew? I admit my ignorance here. I ask myself, what would be the feedback response time necessary to make course adjustments? Because if it were not an artificially "intelligent" craft, and the course adjustments were needed on a minute-by-minute basis, then a remote crew on Earth is not feasible, due to the fact that the asteroid would probably be several light-minutes away from Earth. I'm thinking out loud here.
Getting it there would be easy- no more difficult than any number of flyby probes we've operated in the past. And the control system would be pretty simple, as well- not what anybody would call AI, just a simple servo system. All the tug does is orient itself on one side and maintain a fixed distance by modulating its thrust. That's one thing that makes this system attractive- its extreme simplicity (which also translates to reliability).

Huh, cool. I guess I imagined quite a bit more complexity than would actually be involved.
