I'm really confused regarding this last paragraph, Greg.

Right now, if our authentication info *fails*, why does the checkout
just happen anyway? I mean, if we want to allow anonymous checkout,
why not require that folks login as "anonymous", like CVS does?

As it stands, somebody mistypes their password, and they have no idea
until they try to commit later. It's like they get a read-only
working copy without realizing it.

This is the Big Issue. Please tell me if this is possible.
