Maybe it is just me but when I do earn my Black Belt in Aikido I would like it to be more ceremonious than when I received my Black Belt in Taekwondo.
Aikido is the study of non-resistance. You could kick and scream and make wishes about how you want something to be. Or you can allow it to be how it's going to be. And then you can be.
Or not. : )

FWIW, I recently graduated a student to shodan over the cel phone. He was in the middle of dinner at a nice restaurant with his wife. He'd earned it. I realized it - and offered no resistance.
