I'm a bit late to the discussion here so I'll keep it short, option 4 sounds like the easiest option for me, rip it out root and stem and be done with it.
I'm sure Mr beanie has already discussed this alternative with his fellow modders but I was wondering if he could make an addon mod where option 4 can be used by players who don't want or need that modern ST technology thing.
Damn it, I could even give him some high marks out of 10 for catering to all players as well, would 5\10 be too high Mr beanie, I don't want you to get too big headed as your better half could start whacking you round the head with her rolling pin, I'll leave it with you and your team mates to discuss this option again, and please Mr beanie, make the right decision.
