Is Islam a way to salvation?

Mark Hemingway at NRO:

I was at the NPC breakfast with Wright this morning, and no one seems to have picked up on what I thought was one of the most remarkable comments this morning:

MODERATOR: Jesus said, “I am the way, the truth, and the life. No man cometh unto the father but through me.” Do you believe this? And do you think Islam is a way to salvation?

WRIGHT: Jesus also said, “Other sheep have I who are not of this fold.”

That was the extent of his answer, and after he gave it, Wright backed suddenly away from the podium to gaze at the audience for dramatic effect.

Hemingway then quotes all of John 10:16, which I offer here from the ESV:

And I have other sheep that are not of this fold. I must bring them also, and they will listen to my voice. So there will be one flock, one shepherd.

Does that say what Wright seems to think it says?

Hemingway comments:

As a practicing Christian, I've always been under the distinct impression that Christianity was not to be regarded as part of a spiritual smorgasbord where all options are equally valid, as Wright seems to suggest here.
