Hovering droids like...

[schubertrr]

Something like that one.  

I watched A New Hope again last weekend, and something clicked with these little guys.  What about using a remote controlled drone as the base for the little hovering camera droids?  Like the one following the sandtroopers in the "this door is locked, move on to the next one" scene.  (They also show up in Episode I, floating around Jabba and the race announcers during the podrace.)  
Thoughts?
