This is the novel. Dr_Manhattan linked to an essay by Roger Williams, which discusses where his novel intersects with the sort of things organizations like SIAI are looking at.
I saw the header of the page and didn't look any farther:
The Metamorphosis of Prime Intellect
A Novel by Roger Williams
This is Roger's article on Singularity issues, connecting his MOPI novel to how things might/should happen.

(Roger is clearly aware of SIAI ideas and has referenced Eliezer in some of his posts)
