[QUOTE= Liked this idea on first reading, but then doubt crept in ... how long does key last ? what happens when it runs out and pilot has no spares ?
Ships may be pulled out of warp by pirates with warp mines or by MA (failed warp), if the pilot has used up his key and has no spare, the customer is not going to be thrilled by the warp that now rakes over an hour to get anywhere useful.[/QUOTE]

but now there is no option at all anyway was just an idea to point there are solutions but nothing have done for it! The "key" could last till owner revoke it btw!
