NEX for Pro wedding photography?

I'm wondering if anyone is actually using a NEX 5 or 7 for pro wedding photography -
PARTICULARLY indoor receptions/dinner/dance without aid of any flash.

I would love to see some - having read about good high ISO performance, I would think adding one just for indoors could be quite useful.

One concern is the thing may be too small, and very hard to hold steady (causing camera shake). I currently shoot both A850 and A700 with big glass (two straps and two cameras at all times) for weddings. Heavy, but rock solid. Low light interiors at wide open (f1.4 etc.) are the weak spot of this combo.

so.... anybody doing this?
