The problem with Neuromancer is that a lot of the scenery and the backdrop itself is based on a pre-Tokyo exchange crash economy, in which everyone just assumed Japan would rule the world soon(ish). The whole feel of the story would be lost, I think now that the parts that could, have already come true, and the parts that haven't come true never will.

Snowcrash has a much better shot, since it pretty much assumed corporations (masquerading around as governments, churches, and media companies) will eventually take over everything. The backdrop still works.

Stephenson's Metaverse is a candied playground populated by everyone, ruled by the technological elite and the corporations who hire them, a safe place to which we see the very first danger unleashed. Gibson's cyberspace is a wild frontier rife with danger, populated exclusively by the technological elite cowboys, who risk life and sanity every day. In the modern real life, Internet access is pervasive and a wide audience will accept "OMG this thing we all do IS dangerous, people could get a computer virus!!!" but you will find a hard sell on "you know that cool web-surfing thing, well these guys nearly die doing it, and that is why they are badass, and Case, well, he almost dies a lot." huh???
