Yep, that's pretty much exactly what sprung to mind when I watched this.The University of Planet finishes researching Threshold of Transcendence and builds Voice of Planet, but the Stepdaughters of Gaia pre-empt them and finish the Ascent to Transcendence secret project first, winning the ga-er, movie.
They even kept the mostly-inhospitable atmosphere from Planet.

The Navi also remind me a bit of the "dream apes" from Greg Egan's excellent Diaspora. It'd be amusing if they were the self-reengineered remnants of a transcendent race.
