"This Agreement will remain in effect unless and until terminated by either party"
I take "either party" to mean either Amazon or the other party signing the contract, namely the author. Doing a Web search, I see that "terminated by either party" is standard contract language for "either of us can end this contract."
At any rate,
this page makes clear that you can "unpublish" your content.
"The royalties Amazon is charging, btw, is comparable to what you expect an e-publisher to dock. Are they implying by this that they are the publisher of the 'self'-published books?"
No, though the word "royalties" set off all my alarms, because that's the word Lulu uses when it's legally the publisher. The entry for Violet Blue's book, though, lists her own publishing company as the publisher, with Amazon as the distributor.
I was just ribbing you about Freya's Bower; sorry that I didn't use a smiley face. What Amazon is actually doing is hiking the distributors' price. I just learned from an e-mail list, for example, that Fictionwise charges 50% for the books it distributes. So 65%, while still too high to my mind, is not totally out in left field, as far as industry standards are concerned. (Puts in a grumble here about how e-book distributors in general are totally out in left field.)

"I presume my books there are via mobi and so at 50%."
Yes, over at the aforementioned list, the authors are speculating about whether an easy way to get around the 65% charge would be to go with Mobipocket, whose books are being translated into Kindle formats. Someone on that list mentioned 50% as the discount for Mobipocket; I'm reading the contract to say it's 45% if you want the contract to be non-exclusive. Maybe it's just me, but I'm not sure whether 15-20% is worth the bother, since it appears that the DTP interface gives you a lot more control over the product. But then, I haven't gone through the Mobipocket process, so perhaps that's just as easy.
At any rate, as I've said above, I'm uncertain about the future of Mobipocket, now that Amazon is putting so much energy into the Kindle.
Incidentally, opinion is divided on that other list as to whether Amazon is ripping off publishers or not. I think a lot depends on whether the people posting about this have dealt only with POD books (in which case, they can opt for a 20-25% discount from Amazon, so 65% looks way unfair), or whether they've been dealing in the past with Amazon's e-book program (in which case, this isn't much different from Mobipocket).
