When Bowling was a spectator sport (and being considered for inclusion) it came down to the follow (if I remember correctly):
1. Cost to build a center at each location
2. Lack of spectators willing to pay to offset the cost
3. Too many sports already and too many on the "waiting" list
4. No formal international organization providing standardization
5. No formal training methods
6. No money (bowling would have to donate $Millions to the Olympic Oraginzation to be included).
Some of these things are easy to solve but others are more difficult. The main reason for the development of the Gold/Silver/Bronze formal training classes is to solve the #5 issue. If an international organization was to appear as was supported then we might have the solution to #6 and #4. As for #3 it was decided then that there are "cheaper" alternatives waiting on the list than bowling. Additionally, it was decided that only when one sport was dropped can one from the "waiting" list be added. This one will be difficult to overcome. #1 and #2 seems a bit premature to me, as a spectator sport, I would assume there would be little interest but perhaps different if it was a real sport. And Perhaps many sites would have a center that could be used or would benifit after the olympics left.
