Richard, There was a ton of discussion on this just recently - maybe on CFCDEV - so there might be a bit of validation fatigue out there. On the upside, you should find rich pickings in the list archives.
Basically both of your proposed solutions sound fine. If there was a consensus (not sure if there was), I think it would go something like: 1. Your instinct to remove the reusable validation logic from the controller is sound. 2. Putting it in the service is OK 3. Breaking it out into a separate validation object is also OK, and maybe slightly preferable.
