I've thought this before -- perhaps the MR library should be offered on Amazon/Kobo/etc., with MR listed as one of the authors, for free? With a suitable blurb about the MR library and everything.

And if such good-quality works were already available it would be difficult to sell them.
My thinking was so the books here could be directly integrated into, say, my Amazon Kindle library. Giving the advantage of Whispersync, public highlights, and direct access through the Kindle Store and Cloud rather than always having to go through mobileread.com which is kind of awkward on an e-ink browser.
Also people with the 3G version could access the MR uploads from anywhere.
