Just remembering this deck and thought it might be interesting to this audience. This is the very first public documentation about Rust (Servo is not actually defined in this deck...), Graydon's slides from the Mozilla Summit 2010, dated 2010/07/07.
As far as I can tell, beyond this talk, there wasn't a formal "announcement" about Rust's initial open-sourcing (if somebody knows otherwise please link). It was mentioned the next day on LtU: http://lambda-the-ultimate.org/node/4009
