Well, I just took a look at the references sheet, and I was surprised no to see at least some of John Varley's books in the list. To be specific, I was thinking in: Steel Beach & The Golden Globe: both in the same setting (Earth cannot be reached, thanks to some alien intervention, and humanity lives in the Solar System, and age is not a probelm. While digitalization of the mind or nanotechnology is not used, a lot of other interesting themes show up). Steel Beach follows a sex-changing reporter while he (then she, which is funny, because as a woman becomes much better at almost anything XD) follows a trail of suicides, discovers a group of humans that want to depart from the solar system using a generational ship propulsed by explosions, all that in the Moon, an habitat gestioned by an AI (like the other habitats in the system) that is always connected to the inhabitants (in fact, the AI uses some processing capacity from everybody's brains). Oh, and there is even a thematic park centered in the historical recreation of the wild west XD. Sadly, the best thing of the book cannot be said, because it would be a major spoiler, but it's an interesting reading. As for The Golden Globe, it's related to the other one (the reporter makes a couple of cameos), but shows more of the Moon to Kuiper Belt of the setting, while we follow an actor with a modified body and an interesting piece of luggage in his run from some unfortunate dealings with a hellish version of the mafia (guanxi to the power! XD) from the outer reaches of humanity's grasp to a theatre on the Moon where he wants to perform the role of King Lear under the direction of an old friend. This one is completely centered in the protagonist and what happens around him, how does he travels as a stowaway in spaceships, etc... The Ophiuchi Hotline is extremely interesting, because while it happens in the same setting as the other two, it includes some interesting stuff, like clones, forking and ego stealing. In fact, saving some concrete details, this could be implemented in the EP setting as is. As for the history, is about a scientist and how she is forced to work for a corporation that has few qualms about killing her and loading a backup when she tries to escape. Which in the end leads to a reunion of 3 or more alpha forks of her... The other ones I would include as a reference for some gatecrashing ideas would be Titan and Wizard (I never managed to find Demon, the third book of the trilogy). These two are not in the same setting as the previous books I mention here, instead they are centered in (if I remember right) one of Jupiter's moons, which is in fact a living organism (with a problem derived from its extreme old age: some of her "local brains" don't follow the commands of the center brain anymore, at least voluntarily), with complex ecologies inside. And something with posthuman intelligence and capabilities in a semi-senile state of being and who also happens to be the ruling intellingence of the whole moon (which, by the way, is hollow)...
