Looks like a pretty standard wafer lock, so this is definitely in the realm of possibility. I assume whoever accepts the challenge would need to travel out to your place? What part of town is it in? Is it easily accessible via trimet?
I also highly recommend sending this challenge out to the Portland TOOOL chapter, since this is right up their alley.
