FIREFLY Set in the Same Universe as PROMETHEUS?

Blastr discovered an interestingly awesome easter egg in Joss Whedon's short lived series Firefly showing that it was set in the same universe as Ridley Scott's Alien and Prometheus.

In the opening sequence of Firefly's pilot episode, "Serenity," Nathan Fillion's Malcolm Reynolds is fighting the Battle of Serenity Valley. And losing. But before he's forced to lay down his guns, he hops behind a giant anti-aircraft cannon to shoot down an Alliance fighter. And when he powers up the gun, the heads-up-display reveals a very familiar logo in the top part of the screen:

Looks like the Weyland-Yutani Corporation had a hand in helping build this ship. Why else whould the logo be there? 

This would make sense as Whedon wrote the first draft of the script for Alien: Resurrection. It's fun to think that all of these characters could have crossed paths at some point. I'd like to see that movie.
