Won't the chunks already be loaded due a 'moving' (caused by the item) chunkloader heading their way?

Would it perhaps be possible to say, add a chunkloader function to pipes that only get activated when an entity enters the pipe? (just like detector rails only sent a signal when a minecart passes over it). That way the chunks will only get loaded when they're actually used. Or would this offer similar issue's like you have with tracking items? Edit: As an addon that modifies the buildcraft pipes so you won't have to modify buildcraft itself
