It sounds like DNG has so much variation that applications would still need to support different features from different manufacturers. I'm not sure it (DNG) will really solve interoperability problems. This issue smells like someone is accidentally playing politics without realizing it.
Kind of reminds me of the interoperability fallacy with XML. Just because my application and your application use XML, it doesn't mean that our applications are interoperable.
I suspect that a better approach would be a "RAW lite" format that supports a very narrow set of very common features; but otherwise let camera manufacturers keep their RAW files as they see fit.
