I like the idea of uchronies, but why bringing in Star Trek? It's so far removed from the EP mindset and themes, it's like fitting cubes into smaller pyramids. the idea of the first contact before the Fall is interesting. How things would have changed if the Factors came before the TITANs got infected, for exemple? or what if the Prometheans and transhumans won or managed to keep Earth (which idea I'm not keen to. That's one of my favorite plot in EP, the loss of Earth Another fun idea for an uchrony would be to have a strong Uplift nation, a rival to both the PC and the Jovian Junta or what if the Iktomi never were extinct, but played possum instead. Upon learning that Factors are about to reach out to Transhumans, they come out of hiding and make first contact before the conservative race of the Factors can come and feed bullshit to us. many possibilities to explore without involving the goody-two-shoes federation and Starfleet

In fairness, in the novelization for the first Star Trek movie, Roddenberry did hint that transhumanism of a sort was progressing. The "New Humans" (http://memory-beta.wikia.com/wiki/New_Human) were becoming a substantial minority of the stay-at-home human population, product of increased peace and stability and characterized by the use of telepathy and other ESP powers to produce group consciousnesses. The New Humans disappeared from the emergent Trekverse after that. The basic theme, though, of transcendence is inherent to the universe. In the various Star Trek series, it's almost terrifyingly easy for a precocious individual--or world, or civilization--to accelerate towards a singularity and develop god-like power, featuring even in TOS' premiere ("Where No Man Has Gone Before") and dominating Deep Space Nine. I'd make the case that the Prophets are even products of a transhumanist phase on Bajor: as a unified high-tech world for in excess of twenty thousand years with a population ranking at least in the hundreds of millions, the sheer size of the Bajoran gene pool may have allowed for substantial evolution over time, some branches taking different courses from others, and that Prophets even say that they are "of Bajor". (Oh, but that the Cardassians were _lucky._) Could EP be merged into Star Trek? Sure, if you want it. The question of balancing the themes has to be answered adequately, but I think that it can be done since the TV and film series (never mind the books) did that on several occasions. A relatively easy way to do it might be to take Eclipse Phase at its current point--2143, I think it's been argued, judging from the relative placement of the planets on maps and on Uranus' entering a new season--and merge it with the Trekverse circa 2143. (No Third World War in the 2050s, no Cochrane in the 2060s to attract the Vulcans, no later reconstruction of Earth on solid conservative lines.) Even before the Fall, I think that the Vulcans--and everyone else in the neighbourhood--would have become rather wary by the very rapid de/transhumanization of human civilization. I've joked with friends that the Federation, with all of its technological wonders limited so effectively by a lack of imagination, is basically a desperate effort by the reality-loving Vulcans to try to prevent a regional singularity and sublimation to a higher state of being. Except for Trek's FTL technologies, the pre-Fall civilization that has copies its souls to portable physical substrates and terraforming and uplifting everything is more advanced than the _24th century_ Federation. After the humans' strategic defense computers ravage the homeworld before disappearing, leaving ruin and gates which connect to a pan-galactic network (huh, is _that_ what happened to the Iconians?), well.

From what we've seen on the television the Vulcans are very status quo conservatives, trying to manipulate less advanced species into behaving politely and responsibly using various forms of soft and hard power, preventing interference in the least advanced species through their proto-Prime Directive, and resisting the urge to radically alter the Vulcan species and indeed to neglect potentially game-changing elements of their makeup like their psionics until very late. (And in the meanwhile the Vulcan splinter civilization that is Romulus used naked singularities to power its starships. A coincidence that the Romulans left their homeworld?)
