I am just using this as an opportunity to voice my thoughts about the potential of a Mass Effect mod. I remember playing ME around its release and going back and forth between that and the SoaSE beta in my free time, and finding lots of similarities and possibilities.
The two have similar methods of interstellar travel (in terms of what the Iron Engine is capable of doing.) Since we are all familiar (hopefully) with the way that units travel in Sins, I will just explain the ME side and let you draw the conclusions. In Mass Effect, ships use simple FTL travel to move between planets within a solar system, which still takes a little bit of time. They use the large one-way Mass Relays to instantly travel vast distances. I could see the possible implementation of these by way of removing the phase lanes between stars and using the Mass Relays in the same way that wormholes function
The ships we know of via the codex in ME also have very similar roles to the standard classes in Sins. As we really only know about the Humans extensively from Mass Effect, I believe that they would be the best ships to model.
Here I want to state, I do plan on acting on this eventually, I just don't have the time at the moment, as I would like to graduate High School and get in to college, and simply need to place possible modding projects on hold (school is a bitch right now

). Here is what I have in mind, however, and if anyone wants to take this idea and run with it, that is absolutely fine by me, and I will offer what assistance I can.
I would like to do a rudimentary proof of concept mod, simply creating the standard scout class, fighting frigate, fighting cruiser, Battleship, and Carrier. Any other support classes would need to be completely original, and would require much additional conceptual work, as we already have limited enough imagery of the other classes, save the Frigates (the Normandy).
The purpose of this would be to add the Human Systems Alliance to the already existing pool of races to see if they would integrate well into Sins. I could see this eventually turning into a Total Conversion. But would like to start small and build up from there, adding in Support classes and expanding the research tree to turn them into a truly unique race over time.
Sorry for the relatively large post, but I like to be thorough. Anyone have any thoughts?
