So I would imagine it would be up to the ME to set the DialNorm level during mastering on each CD (or any succeeding audio format),if it were implemented for audio playback. What's to stop everyone from setting the DialNorm level to -1db?

I thought it was an absolute value of attenuation, but not to quibble.
Cheating will not be allowed if this thing is not going to turn into a fiasco. Someone has to create a standardized meter and an unambiguous definition and I assume someone at the plants has to be able to confirm or reject the dialnorm setting.
It sounds complicated and scary, but I see no alternative if we are looking to have sound quality in the future media.

I'm assuming that DialNorm would also require new decoders in all playback devices as it looks like it is tied to Dolby decoding for either DVD or Broadcast purposes.

Well, "coding" is not necessary to implement dialnorm. All you need is metadata. This can work with a non-compressed format as well as a data compressed format. There's even enough room in the current CD subcode for dialnorm, but it's too late to implement a standard.
One thing that would have to happen is that all new players for the new medium (e.g. "blue ray") would have to have metadata decoders in their hardware, implement the metadata (dialnorm) in their D/A converters and if external converters are used, metadata will be required to be communicated and dialnorm as a standard in the DAC.
Since there is a new medium, there is room for the new rule....
It would be VERY cool if it could be made to work.
