Please, please, please blog your attempt at going polyphasic. There aren't a lot of rational records of people trying this; and it's a really interesting topic (to me, at least).
I'd try it myself, but for now my commute prevents me from being able to do it.

I plan to. I'm shopping for an RV at the moment, and plan to hit the road on January 1st, and I'll be blogging about the process of going mostly off the grid while still running a company. Switching to polyphasic sleep will be a minor change in comparison, and so I'm cramming a number of life alterations into one bunch...since I won't have any habitual behaviors that remain unchanged, I'm going to take the opportunity for self improvement on all fronts (eating, exercise, environmental impact, getting out of my comfort zone, etc.). I've read that people have an easier time altering habits, like smoking, when they are out of their normal routine, like when they're on vacation.
This sounds like a great plan, I think you will have an interesting journey! I can confirm that the absence of daily routine triggers facilitates change to let go of undesired behavior. For instance, it was way easier for me to stop smoking and exercise every day when I spent the summer in California.
I loved it but my life didn't accommodate it. It was much easier on work days because I could sleep both ways on the train, one nap in the middle of the day, and then make it through family duties at night before I needed another nap. My wife didn't enjoy the scheduling difficulties on the weekend and it's not something you can switch on and off on short notice (takes about 5-7 days the first time and 2-3 days to start back up). There's a couch at my new job and I'm considering starting up again.
