FYI: Here is the current multiplayer mod for KSP. It's not official - but until the developers do it, it's all we have.

Here is a list of known issues with it.

Quote regarding warping: 

And I can use warp as much as I want, anytime I want?
Yep--normal "on rails" warp is always available, though "physics warp" isn't.

But... how?
The big problem that immediately comes up when allowing players to use warp whenever they want to is that forcing everyone to go into warp is unpractical, and otherwise your local copy of the solar system wouldn't be synchronized with other players (so the planets and moons would be in very different positions relative to each other for different players). KMP gets around this by allowing players to play in multiple timeframes (or "subspaces") simultaneously. You can sync with any player that's "in the future" relative to you whenever it's convenient.

That sounds complicated. Is it complicated?
For gameplay purposes, at least, it's actually really simple! Need to go to warp for a few years to position that shiny new Jool probe? Go ahead! Want to build a new space station with your buddy afterward? Just sync up and you're good to go. That's it.

What happens when I'm not in sync with someone else?
You'll still be able to see those players and what they're doing in-game--you can chat, send screenshots, share designs, etc, but you won't be able to interact with any in-game vessels that those players control. Vessels from the past or future turn translucent so that you know that you won't be able to affect them. If the other player is in the past, KMP tries to predict where they'll be in the future and shows their ship at that location. Keep in mind, though, that since the ship is still being manipulated in the past, the predicted future location can rapidly change. If another ship has been manipulated in the future, you're effectively just watching a recording of events that have "already happened" play out.

Won't everyone just be out of sync all the time?
It depends on what people on a particular server are doing, but yes it's totally possible that everyone on a server might split into their own subspace, and that's A-OK! When you first connect to the game you're always placed in the "latest" subspace currently on the server, and if you ever want to directly interact with another player the most you'll have to do is click a button. Vessels that aren't under active control by another player and that haven't been touched in the "future" (relative to you) are all available.
