Intelligent Minecart Routing in Minecraft

I've made a completely automatic minecart routing system for vanilla Minecraft, which uses a series of independent junctions and stations, along with data carts filled with "bits" to route a player from one station to another.
Because I can use two different non-stackable items as "bits", I can suck one bit out of the data cart at each junction, and see what it is in order to determine if the junction should switch. Using this basic principle, one could in theory have a network of practically unlimited size, without any obscene lag, and players could navigate through it with just a few button presses.
