If 2+2 books, in particular HOH and TOP were available in an audio format there is an extremely high probability that I would buy them.

I do audiobooks. I have, I believe 15-20 on my ipod. I have been considering asking about audio formats for weeks now after seeing Phil Gordon's book on audible.

And to toss another idea out there, a 2+2 podcast would take about nine seconds to be the #1 poker podcast out there. Lessons, hand analysis perhaps of hands from recent televised tourneies, interviews.
