NewsForge has a very good overview of the problems with Creative Commons licenses for Debian. In particular it covers the work that myself and members of the Debian Creative Commons Workgroup did to bring the CCPL into compliance with the Debian Free Software Guidelines. It also tells about how we had a draft version of the license that was DFSG-compatible, but how that was unfortunately changed. (More info at the Debian Creative Commons Workgroup report.)
How are things going with the public review process? Not so well. The main sticking point remains "parallel distribution", which was part of the previous draft license we reviewed, but which was pulled. People have some very emotional reactions to DRM, and they tend to sacrifice developers' and users' freedom in their quest to "Stop DRM!!!!1!".
Please, if you are at all interested in seeing DFSG-compatible versions of the Creative Commons Attribution (BSD-like) and Attribution-ShareAlike (copyleft) licenses, let people inside Creative Commons know. The cc-licenses mailing list is the main conduit for public feedback on the next generation of the licenses. Even an email that says, "I want the Creative Commons licenses to be compatible with the Debian Free Software Guidelines." would help tremendously.
