Apple-EMI, no-DRM's fate hinges on these three factors

To me, the most vital calculation in the just-announced no DRM deal between Apple and EMI isn't the fact that you will be able to purchase restriction-free EMI tracks via iTunes for $1.29, not 99 cents.

Tke key metrics would be:

How many more buyers of legal music will be woo-ed by the no-DRM, 30-cents differential?

Will those new buyers stop illegal file trading- at least as far as EMI tracks are concerned?

Will the commerce at the 30-cents-higher level be adequate to serve the interest of music companies and artists who sign on- considering that the ability of purchasers who buy EMI tracks at $1.29 to swap files with friends is likely going to cannibalize legitimate sales of these tracks by the friends of those who have recommended these tracks to begin with? 

What do you think? Is paying 30 cents more for no DRM a good deal?
