Ooooooh...maybe a drone that can be controlled via an iPhone. Or better yet, controlled by a Droid. A droid controlling a drone? We are one step closer to no longer needing humans.
Dan, I was going to suggest a built-in grill of sorts that could be whatever height you want and be free of anything underneath it to make room for your legs in front of you. Built-ins aren't cheap, however, and it sounds like you're going to wait a bit now. Maybe that's a good goal for you to have! Up and grilling in no time!
