See, for example, perhaps, this album from the Wu Tang Clan:

That's a very interesting read, and I'll have to give some thought to the implications therein.
I was originally thinking of something more along the lines of Radiohead's In Rainbows, released online for a donation, but may combined with a kickstarter-like fundraising effort to pay the upfront costs.
1. The asset takes requires a significant amount of resources.
2. The asset will require all resources in order to distribute.
3. No further resources are required after distribution.
Music, books, art, and even software that does not require updates would fall into this category.
