This format has native support in Vista and MS will be doing its best to increase its use, so it will almost surely be important.

Yes, but that will be the future. I do not see any reason to help that format to spread. It even does not support large files (> 4GB), so what advantages it has over the old TIFF with except of the new codec? When that format will become notable we can start implementing libtiff support for it.

You seem to be reading the old version of the license when it was released just for evaluation, MS released the actual license terms later and the latest version of DPK has even more liberal terms.

Nope, I am reading the HDPhoto_eula.txt from the DPK distribution. It has a number of clauses conflicting with libtiff distribution terms. I can list some of them:

" * Third Party Distribution. You may permit distributors of your Licensed Products to copy and distribute the Distributable Code as part of your Licensed Products, provided that your distributors are legally prohibited from modifying, and do not modify, the Distributable Code and/or the Licensed Product in a manner that causes the Licensed Product (or any third party product in which the Licensed Product is incorporated) to become non-compliant or incompatible with the HD Photo 1.0 file format (a.k.a. the Windows Media Photo 1.0 file format) as defined in the specification(s) provided in the software."

"ii. Distribution Requirements. For any Distributable Code you distribute, you must

"iii. Distribution Restrictions. You may not

Definitely, all these makes that source code not compatible with libtiff license and generally non-free. So the only option remains is an external linking.
