The idea is that if we make a circuit of wifi and conductors or by any means in a save/stamp then we can use it from another different save like using that circuit from other save.this will definately increase speed and we will be able to "hide" our circuits. 

with "link".it was just a suggestion like a save will work exactly as it works now but with very less parts! because parts decrease the speed.the main circuit will be in other save maybe a new code which works like sign(i.e.{c:"saves id","description"}.AND also i have said nothing "about layers"!
