From what I understand based on the article (and someone correct me if I'm wrong here), the Relay Network feature will affect 2 Game Systems: probe control and science transmission. For probe control, I see only 3 ways to handle occlusion: 1) The player loses all control of the probe; 2) The player retains all control of the probe; 3) The player retains some control of the probe. #1 is unreasonable (and unrealistic), #2 means the feature will only affect 1 Game System, making #3 the likely solution. To implement this they could say attitude control is removed but throttle control remains (or vice versa), but that doesn't make much logical sense. So, the most reasonable solution seems to be some form of "programming" of the probe. Allowing it to execute maneuver nodes is likely the best way as tater most recently mentioned, and for the reasons he gave. But given that the current probe control mechanics limit which can be used for SAS functions, it could end up that only some probes can be "programmed" at all. If that's the case, I hope it's only the very early one or two probe cores which lack that functionality. For science transmissions, the solution's probably obvious to anyone: No transmissions without line of sight to Kerbin or another probe which itself has line of sight to Kerbin. Care to elaborate on those other ways? I'm having a hard time imagining what they are.
