The username is the avatarId, which is always a string and always
present, is it not?

Anyway, never mind - I get the idea - the page is the avatar and should
be acting on the users behalf. I don't *agree* with the idea, but I get
it.

I think I'll just override the nevow traversal mechanism with something
more to my liking on, and attach my principal "object" (which *I* think
is the avatar, not the web page) to the request during locateChild on
the root object.

Thanks for the rapid reply.

Cheers,
