Haha, clever guy. I did something similar with PeterKaan, works rather well 
Be careful about moving your fleet about. If I was Oldry, I might leave a few fleets in space set to Pirates in case you have ships moving around.
Is anyone able to fund a scout ring around his planets? If we sit them all just outside his sensor range, we should be able to catch most ships that move through it and see where they're heading. Hopefully, since it's close to his planet, his ships won't have enough speed to slip through it (like seems to be the case when he wandered through my ring with an arc).
My current plan:
Deploy all available discretionary fleets to Airstrip 3. Upon arriving, scrap. Build 1 scout and 1 frigate at a time until a large enough sum of resources has accumulated and enough subspacers have been killed that I can build a fleet large enough to kill his subspacers... or just build PD.
