Yes, this is online right now, but it may be removed entirely in the near future. This is an extra on the Thor DVD. Its got Clark Gregg as Agent Coulson, and fills in some story between Incredible Hulk, Thor, and Avengers. And Iron Man. Apparently we can expect more shorts like this leading up to Avengers.

Another short titled “A Funny Thing Happened on the Way to Thorís Hammer” in also expected soon.

After the jump, see Joss Whedon talk about making Avengers.
