Javascript could be used to generate the cookie which is then passed
back to the server with each request. This would save having to make
sure a value was posted or passed on the query string on each request.
Don't have time to think about how good this would be for
authentication but I think techincally it can be done.

Sounds completely bogus to me.
The cookie is typically generated by the server, as a response to an
authentication event (single or multi-factor). The cookie is then used
to maintain that authentication from request to request.
There is NO authentication component in such a cookie. It is created by
the SERVER, and as such CANNOT qualify as an authentication factor at all.
