Here lately I have heard a large ammount of noise about putting multiplayer into KSP. I believe i may have a way of doing so that is, if nothing else, doable, if a bit cumbersome. My idea is based around the warp drive mod. (The one shown by Scott Manly as being, "not OP".) If you could disable the time acceleration feature and add in different kinds of warp drive, you could, in theory, make it so that you never actually 'need' time acceleration. You could have an inter system warp drive. This could be good enough to get you to say.... menmas in five minutes? Also, have it use normal fuel, but at a massive rate, so you have to sort of feather your use of it. You could have an inter planetary warp drive. This should be able to get you to the near planets in 5 or so minutes, and out to the farthest in like....20 minutes. I could see this using nuclear power to run. You could then have an inter stellar warp drive. This could have the capability to get you to the far planets in 5-7 minutes. This would, of course, need to be run off anti-matter. This, IMHO, would be do-able, and playable. Not exactly the fastest time from planet to planet, but a 20 minute round trip would be reasonable. Sure, that is alot of flying around, but add in a chat function, and you have a decently functional multiplayer. If you did this, it might be a good idea to create a sort of....anti matter storage container part. One that allows a player to transfer their stored anti matter to it, and to take anti matter from it. This could be put on a space station that orbits kerbin or other planets. This could be player locked, or a server bank, of sorts. I could see older players offering a sort of 'towing' service to newer players. Have the newer players dock up onto their ship, and then have the older players warp drive them out to the farther planets. This would allow newer players to still get out to the farther planets, while giving older players something to shoot for. (That is, a ship that can get a docked ship to another planet. (and back, if the player is feeling kind...and doesnt want to strand noobs out in space....but...who would want to do that? -shifty eyes- )) Just my thoughts on how I would try for multiplayer....if i was a coder.
