Xterminator, it sounds like you answered all of your questions yourself....
In response to your main question, Christ is the author of EVERYONE'S salvation. Just because most of the world has been raised Buddhist or Moslem doesn't make their religions the correct ones. Not that I'm trying to degrade them or whatever...I have a few Islam friends, and I really respect their way of thinking and how they do things, and I would never demean someone's beliefs.
I was trying to think of a "nice" way to answer your question, sort of pad it or whatever, but when it comes down to it, Christ is the only way for anyone and everyone. If they haven't learned of Him yet (or at all) in this life, they will receive an opportunity to accept Him and change, or deny Him and their eternal rewards.
Sorry if I come out a little boldly, but I am firmly rooted in my beliefs, and I wish I could just shout them out to all of you.
