Think outside the box! That's my short answer prior to reading a single post on this thread (just its title). I reserve the right to update this post after reading the posts, of which I'm going to do now.

Edit 1: So far, I like how you posed the question in the OP.
Edit 2:
I was selling some coins to a guy in Starbucks and it was awkward because he was late and my laptop battery had died and I accessed an instawallet with too many coins from his laptop so I needed to send them to myself... but I didn't know any of my addresses since they are stupidly long. BAM FIRSTBITS. Now I pay hosting fees and make no money, but girls are writting them on their skin so one day it's all going to work out.
Somebody tell me how this business model could even begin to fail.
Edit 3:
Also, this board will initially try to rip apart your idea. This is a good thing. However, it can be a little discouraging and sometimes people just want to be jerks and shoot down your idea. I have proposed ideas on this forum I thought were great, and got terrible responses. My most recent concept was ripped. Heh heh
But, if you think you can pull it off, go for it! Just don't pay too much attention to the peanut gallery.
Good Luck!
And some people will outright steal your idea and call it their own, like what happened with my Twunker idea.
Finally Edit: You folks who commented did a fine job.
