UHHHHH --- DOH! IMHO, this would not be most excellent, since as an
author, I'd like to control where people start out.

yah, because the first person to find Adrian's Treasure Lode
could just make an WWWAnchor to it, so that other lame-o's
wouldn't have to go theough all the fun of finding it.

(of course, even without this, you could still achieve
your goal, by cesating a world with the default camera you want
and WWWInline-ing the world you want)

(and CGI's might let you prevent people from requesting
the starting camera, but anyhow)

I'm still waiting for browsers to implement map POINT properly,
so, I don't think this proposal would help...

The Texture coordinates map though, would be of use.

Cheers,
Adrian
