Cost - The benefit of pour over is you are able to offer multiple coffees at once. You would now need one grinder per coffee offered. Also you might need to upgrade your electricity.
Space - Footprint on the counter. Our space is designed to have 3 grinders. Right now we have 2. Where the grinders are placed is key as to not create a wall between the barista and customer.
Many home users already weigh their beans per dose for espresso grinding (just as many people doing manual pour-overs in coffee bars are already pre-weighing their doses.)
The grind setting of an espresso grinder needs to be tweaked a bit initially when doing single doses due to the fact that there is no weight of beans in the hopper pushing downward, but once grinder is calibrated for those beans and conditioning it should not need to change much. The issue with the "popcorning" effect of single doses in the grinder throat is easily addressed by leaving the hopper off entirely and putting a tamper into the throat where the hopper was (this woudl require bypassing or disabling the hopper safety interlock that Mazzer has on current generation conical grinders.)
No reason why one grinder couldn't be shared among multiple coffees just as single Ditting or Mahlkoenig is already being shared this way in most bars.
