I actually turned part of my 2004 Nanowrimo into a shorter erotica story (one of my characters went off on a tangent and wrote his own story) and sold that.
I'm currently editing the two most recent for an interested agent. But despite this, I think I'm becoming disillusioned with Nanowrimo. I've won 5 times. Yes, I can write very fast if that's what I'm trying to do. But I think I'm having to spend extra time on editing so I'm not sure if it would be faster just not to worry about 50,000 words in November. Though I do like the community feel of Nano.
