New Creative Commons Licences

I mentioned en passant the new CCZero licence, but here's news of yet another:

CC+ is a protocol to enable a simple way for users to get rights beyond the rights granted by a CC license. For example, a Creative Commons license might offer noncommercial rights. With CC+, the license can also provide a link to enter into transactions beyond access to noncommercial rights — most obviously commercial rights, but also services of use such as warranty and ability to use without attribution, or even access to physical media.
