Think of it as the highway that connects the cities. (Cities are fedimints) Early builders were building one way back end gravel roads. (Liquidity demands that create choke points on the one way roads). 

That problem is being solved! 

 That's exactly how I have been visualizing it. My curiosity about fedimint is how large these federations might become... will cities have them or moreso families? Maybe somewhere inbetween. 

 all of the above
