We're almost there folks.

The days of the subsidized Kindle -- perhaps even down to zero -- may be on the way.

Amazon.com (Nasdaq: AMZN) announced last night that magazine and newspaper publishers will be able to begin receiving a 70% slice of Kindle-based subscriptions, net of delivery costs.

The beefed-up royalty kicks in next month, and publishers have to allow their online publications to be made available across all Kindle platforms and in all geographical regions. It's a fair compromise, given that Amazon made a similar offer to book publishers earlier this year. We've come a long way from the Kindle's early days when it was Amazon collecting the lion's share of the resulting revenue.

This doesn't mean that a $100 annual subscription will net a newspaper $70. The delivery costs will add up. Amazon's FAQ for publishers explains how the delivery costs -- currently $0.15 per megabyte -- will play out.

For example, the delivery cost of a newspaper that delivers 9.0MB/month via paid delivery methods is $1.35. If the publication costs $9.99/month, then a publisher would earn $6.05 for each subscription.

Obviously the breadth of different publications will vary, but if the example is close to the average, a royalty cut of 60.5% is still generous.

It's about Times
The top-selling newspaper on Kindle's digital storefront right now is The New York Times' (NYSE: NYT) namesake daily, fetching $19.99 a month. If the bandwidth costs would also equal to $1.35 a month, The New York Times would be receiving $13.05 a month.

Now let's tackle the subsidization model. AT&T (NYSE: T) knows that it can shave hundreds off a new wireless phone, because it can make that back through at least two years of contractual connectivity. Can this work for publishers? If The New York Times would offer a free Kindle to any subscriber committing to two years of its namesake paper, where's the harm -- especially if it aims at out-of-town readers first?

Over the course of two years, The New York Times would receive $313.20 in royalties. Is it that outlandish to offer a $139 Wi-Fi-based Kindle -- or perhaps even the more accessible $189 3G model -- for free?

Cruel math
The next two best-sellers -- News Corp.'s (NYSE: NWS) Wall Street Journal at $14.99 a month and Gannett's (NYSE: GCI) USA Today at $11.99 a month -- would require trickier math to make it work, but isn't it worth a shot?

Print circulation rates continue to shrink. Why not be the first newspaper company to blow this model wide open by subsidizing Kindles or perhaps even Barnes & Noble's (NYSE: BKS) Nooks? Who knows, maybe Barnes & Noble may even lend a hand to the subsidization process if it means folks will be carrying around the Nook for two years and drumming up incremental digital download sales.

If the math makes sense -- and keep in mind that many subscribers will likely continue to stick around after the two years of contractual obligations -- the time to act is now, just in time for the holidays.

If The New York Times were to offer two years of prepaid service with a free Kindle included, wouldn't it take e-readers to a whole new level? I think so.

One thing for sure is that this is the kind of math that will never work on Apple's (Nasdaq: AAPL) iPad -- but Amazon may want to encourage its publishers to consider the possibilities before a newspaper company begins offering a half-priced entry-level iPad under a similar arrangement.

The Kindle isn't a razor, but if they play their hands just right, the newspaper companies may be trading in their printing presses for blade factories.
