I'm sure Chris will bring in the lessons they've learned at Adobe when creating their PSB/Large Document Format.
PSB was only a minimal change to the PSD file format to use 64 bit offsets. But changing the file extension and version number did let me clean up some things that were held back by compatibility issues (when you have to be compatible with everyone, it's not easy to change the file format).
What are the obstacles to publishing the PSB/Large Document spec and basing "big TIFF" on it?
