I have also been concerned about the proliferation of impure vrml
files across the internet. So, in an effort to stem the tide I've
decided to start keeping a list of all the URLs that claim to point
to VRML files but do not. It's called the VRML dog list. I will
also be maintaining a page of legitimate links to VRML objects
which can be added to by any user on the net. Along with these two
pages, I have provided a page with a fill out form VRML authenticator.
Users may submit a URL for testing and if it passes the test, it will
be added to the legitimate list. Basically, this page is just a front
end to the Qv library. I haven't had a chance to completely debug it
so don't be surprised if you see an error message. :-)
