'It doesnt matters what percentage of users are there'

It matters a great deal how many people have the shockwave plugin installed on
pcs,
you get a high end site for a corporate client, they are not going to want
users to wait for plugin installation even is shockwave.
Outside gaming sites, not many people appreciatte plugins and cannot be bothered downloading them, many might even be wary as they have read a little bit about viruses in their newspaper on way to work.

Thats why currently for simpler 3d I prefer the flash route as more people have the flash plugin on pcs and macs, its higher than 60 percent.
I would love shockwave to be pre installed on pcs and macs.
