LoginManager will behave just like your outline, if you give it a
BasicCookie LoginMethod, and a BasicAuth LoginMethod, in that order.
LoginManager does not climb up the acquisition hierarchy, as that is
properly the province of ZPublisher to do.  It will provide the anonymous
user, if it is a top-level user folder.

Not as far as I can see.  You shouldn't even need any custom LoginMethods,
the out-of-the-box ones should work just fine.
