Add my vote for the auto opening door - or at least something you can open with a switch you can kick. I hate juggling a big tray of meat in one hand while trying to open a door with another.
Likewise, a foot operated sink would be a real plus, along with soap and paper towel dispensers with proximity sensors.
A goose neck sprayer on the sink would be cool as well. In fact, I think a large sink with attached counter with gutter would do it for me. I think I could confine my mess to that and would not need to hose down the entire room. It's not an abattoir!
