title: "Pathfind" a linked list?
body: <p>I'm toying with the idea of making a sort-of virtual network "simulator" if you will. I wanted to put together something of a linked-list (or best I can describe it as).</p>
  
  <p>Imagine it like a normal IP network made of objects. Then passing messages along them between remotely-linked nodes. Even if I have to "cheat" to some degree by being able to know the path, and instead update all relevant nodes in the path that a message supposedly through it, without actually -moving- the message object -through- the nodes. I'd still need to know what nodes needed to be notified and thus still at the very least need to know the path.</p>
  
  <p>So, it's not exactly a linked list. Or maybe I don't know the terms I need to convey the issue, but pointing me in the right direction, or of course some code examples, would be delightfully appreciated. Thanks :)</p>
