Would you be interested in a service which automatically uploads all of your high scores and game settings so you could share and compare with others? Your settings would get backed up constantly so any issues you could restore them.
It would require minimal effort on your part and probably a small fee to use the service. It could also store your in game shots for the high scores and display them if you wanted. This would work with all JJP games.
Could run online tournaments, homogenize game settings (extra ball, difficulty) for the tournament (so everyone had the same rules), etc? Could even do a prize money situation. Could attach video footage of the game (or live stream) to the entry as well for verification.
