I love Snow Crash too, for what it is, and I'm sure someone could make a worthwhile movie out of exploring the concepts, but then I'm not really sure it's worthwhile, as it wouldn't need to be strictly based on that work.

But if someone is hoping for a scene accurate depiction I'm equally unsure it's possible, or that anyone would want to see it, between everything from the "radical"(/Rule of Cool) Carmageddon pizza delivery for the mafia and variable rollerskate wheel sizes to the main character literally being named Hiro Protagonist.

It's a great nostalgic time capsule for me, which also spawned a lot of other great works, but I'm fine with leaving it as that.
