I get insane adhesion using ABS juice on a glass heated bed. I've reduced the bed temp to 95 C and can get prints off reliably. At higher temperatures I was breaking the glass plates before the prints would let go. You will need to experiment with the ratio of ABS to acetone to figure out what works best for you.
I haven't found the fumes from the acetone to be a problem, they dissipate very rapidly in any decently sized room. Ventilation is recommended for printing ABS, however, so this should be a moot point.
Not sure how well printing ABS on an unheated surface would work. My gut feeling is the temperature differential from the nozzle to ambient on the bed is going to be high enough to cause part warp issues, even if the parts stick fine.
