Specifically Novels and Music in respect to NaNoWriMo and Kompoz.
The idea in a nutshell.
NaNo novelists may write song lyrics as a part of their novel. They will license these (the lyrics, not necessarily their whole novel) as cc BY or cc BY-SA. There will be a place in the forums on kompoz or nano or better yet some shared forum where lyrics written each day may be posted.
Kompozers, for their part who wish to take part, will choose from the lyrics each day and try to have a song done around those lyrics by the next day. This song(s) will featured each day on the nano site.
Alternately, for the NaNo novelists who do not wish to write lyrics themselves, there can be daily suggestions on the kompoz site for BY and BY-SA songs whose lyrics may be included in their novels. (Special permission must be granted by the lyricists putting forward BY-SA licensed suggestions to include the lyrics in an all rights reserved (or other licensed) novel.)
