Casino game API: viable?

Based on some posts on Products Wanted recently I have to wonder if it'd be worth proposing a common communication API for casino games.

Since at many casinos, there are many scripted objects by many different authors all providing effectively one experience, it would be nice if they could all communicate with each other (to allow for things like happy hours, bonus tokens, players' clubs, whole casino jackpots, etc..)

Does this sound like something reasonable? Or is it too much of a security hole and/or commons tragedy?

Well, It would mean all the creators working together... A rare thing at best in Sl.

However I would love to see this happen
