@10:45pm listening to The Hobbit and watching it out of the corner of my eye as I iterate over this.  Really it should have been designed ahead of time but this will get a decent solution quicker.  I have the round trip working, but I now need to have background.js call the spider function it was asked to call in the case of curse (it'll do the save).  I intend to write a spider.handle_background_event and spider.handle_background_callback for either side of the exchange.  Must refresh my memory as to how far I got on this with the save_video call (which was easier because it was one directional).

@12:08 Wrapping up for the night. Tomorrow I will need to create those functions and write a wiki, perhaps, about the various functions of interest, such as executeAlternateMode and so on.
