And as was said during the thread, what happens if theres a lake, a building, a playground, etc in the middle of the straight line? What about if the 'straight line' crosses outside of the area, say for example if you had an L-shaped area. > Are you certain no routers can do that? I think this is what it boils down to, that some routers may be able to do it, but I suspect most cant/wont. As a general rule, routers route directly from one node to another. along a way and only leave that way at a junction. There is no reason you couldnt make a walking router, which doesnt have the restrictions of having to follow a way, but at the moment this isnt how most (all?) of them work.
