So, back to option 1, what would it take to get this ball rolling? Would Adobe consider producing an updated specification that addresses this?

Yes, but that will take a while (our managers tend to put feature development ahead of standards updates ;-). I'm already planning to update the spec. for a new predictor and general cleanup (integrate the tech notes, kill the obsolete JPEG section, etc.).

Would it be helpful for the libtiff team to go ahead with prototype implementation of the new format for "test driving"?

Yes (in a branch, of course!).

I am personally very in favor of specification documents developed concurrently with a couple of interoperable implementations of the specification.

The best idea would probably be setting up a TWIKI site to keep an ongoing list of differences from the TIFF 6 spec, and include any implementation issues we come across. I'm not sure if we'd want it fully public or private.

Steve's Alternative 1 pretty much captures what I wanted to accomplish albeit at the cost that older readers can't possible get anything from the new files till updated.

That's why it really needs a different file extension.
