I was thinking more along the lines of WP collapse after only a turn or two. As far as stable supply lines went, that was what the gates were for.

Diplomacy would be a problem. Has anyone tried putting an inpenetrable cloak on a wormhole? Could be a way to maintain contact without having access to the WP.

I figured that there would be little hope finding a sector-limited warp close prevention ability (though that would be ideal). Oh well, on to plan B.

I was thinking of having a special jump gate "base" that has an inherent repair 1 ability and had but one component, the system WP closing preventer that is desrtoyed on use. That way you could 'use' the component (ie. destroy it) so that unwanted warps could be allowed to collapse before restoring its stabilizing influence. If you wanted to delay repair (one turn might not be enough) you could include modded life support modules that also have "destroyed on use" that could be nixed to give additional time. Since most sane individuals have ship control components posted higher in the repair hierarchy they should be repaired first.

Tis an idea. How well do you think it would work?
