I'll admit I wasn't thinking of databases when I posed the question, and you're absolutely right about sessions. Anything with a log-in would be quite difficult, and out of my league to even imagine.

As for alteration of pages, what about "hashes"? Isn't the point of a hashsum to make sure the torrent is correct? My thoughts of how this process would work are:

1. You browse the internet as usual, except for a browser add-on that would check links to see if they were available in torrent form.

2. As you click on a link, your browser either loads the webpage in torrent form, or saves the site in torrent form for seeding.

3. More users = more sites in torrent form = faster browsing speeds.

Again, wouldn't work with log-in sites, but for something static like Wikipedia, wouldn't this be incredibly helpful for cutting costs, reducing server load, etc? And whenever a page is updated, Wikipedia simply uploads the new version with it's new hashtag for browser checks.

I hope that clarifies my thinking. So is this a good idea at all? Or still fraught with downsides?
