a warp point opener constantly trying to get through will not work. i had one trying that in diplowar 2, trying to break into one of Dragonlord's systems with 10 warp points. he was able to close one, and open one the next turn, and i was not able to get one inbetween. i think if i had been a lower player number than him, that i would have been able to open one before he could. but i could not open in the same turn that he closed.

there would probably be a similar problem with the system shield. you could not open the turn the facility was scrapped, and you could only open after it if the enemy was a higher player number than you and/or he did not open a full 10 wormholes to prevent you from opening any more.
