Um... I understand the difference between global and rolling shutter.

I'll take your word for it.

But I think you are missing my point which is that sensors need to be made to support global shutter as an acquisition method.

Nonsense.

Maybe you know something that I don't but as far as I knew, the sensor on the BMCC is not a global shutter sensor.

Actually, if it uses the Fairchild [color=#282828][font=helvetica, arial, sans-serif]CIS 2051 [/font][/color]sensor like many think it does, then yes, it can be read either rolling or globally, but that's beside the point, as we're talking about mechanically globally shuttering the sensor while it reads in rolling mode

So, you can't simply glue a rotary shutter onto a digital camera and expect it to produce global shutter.

With proper sync, [i]yes you can[/i].
But hey, maybe an lcd shutter beats a rotary disc for noise, and bulk. The Tessive is now $2,000 and for most cameras can do the job...
If I was more of an electrical engineer, I'd repurpose a pair of active shutter lcd glasses like this guy: http://vimeo.com/5976527
Dan Hudgins has made many insightful posts about this topic and I'd be curious to hear his thoughts.
