Remember a couple of years back the forums were filled with threads about the unbalance economy, and the lack of a good resource sink ... good times.
Oh the irony.
Why would you want a resource sink? Doesn't sound like a positive outcome. Better that there be things you WANT to buy w/ your resources; than 'toll roads' in sector space or things that suck your resources 'just because' cryptic can't find a good way to have you voluntarily give up your resources.
