Although Orci says that they're still trying to find a way, they've struggled with the Trek sticklers and how to deal with Kirk's death in Star Trek VII. Now things are further complicated by the writers' strike -- they can't make script changes until the whole thing is settled. To me, it seems like they're just trying to appease Shatner as much as possible, although I don't see why. The way everyone is talking, you'd think that they're trying to figure out how to write a vampire into an historic war drama or something.
If they want to have Shatner at least pop up, without being able to write it into the script, they could always have Kirk look in a mirror, or some reflective surface and see Shatner, and what Kirk will become. Back when they could still mess around with the script, it wouldn't have been hard for Spock to muse about what his life would be like had Kirk not died, or the Vulcan seeing the different crew members morphing into his once-friends. Or heck, even a daydream where he talks with an imagined Kirk about whatever his role is in the film. But the "possibility" will probably just sit there until the production is finished, and when the Enterprise zooms onto the big screen once again, it will be without Shat.
