Presumably he has a good idea of the possible market based on his digicue sales. I think this cue ball would have to work in tandem with the digicue to get a full set of meaningful data, so current digicue owners are probably the target market.
C'mon man. Even if, and its a BIG 'IF', you could embed the necessary sensor/elec. package in a cue-ball you'd still have to get it balanced to roll like a real ball. THEN, you'd have to market the thing. How many do you think would actually get sold?? I'm sure there's a fair number of techno-geek pool players out there but do you really think this thing would be a break-even proposition much less make $$?? IMO this is nothing but an orphaned solution looking for a problem to move in with.
