Cool website. The trailer played fine for me, it started immediately.
I've actually worked with a lot of your actors. Melissa DaPonte was in my first short film I ever directed, I've worked with Steve Warren on a ton of stuff and April Billingsley was in our short for the 48 Hour Film Project this year. Cool!
As for the trailer, the main thing that I didn't care for was the end. I never liked shots in trailers where people are talking but there's no sound. It's like I'm thinking the whole time, "what is (s)he saying?" The main thing about trailers is you need to show action, movement as much as possible, there's too much "talking heads" here. It sounds like an interesting concept, I feel like I need to see more. Feel free to play around with time a bit... the trailer doesn't have to take place in sequence, so why not start out with an attention grabber, like the gun shot? I don't know if it's possible with the footage you have, but you might want to eliminate the "white wall" background as much as possible. It just has too plain a look to it (this is the same in your feature as well).
At any rate, I think if you can hook the viewer a bit sooner (and keep them hooked), you'd have something which may generate some interest.
Hope that helps...
