I'm using SVN head. Actually, grubbing round in the source, it looks
like putChild comes from ChildLookupMixin, which Page subclasses, but
SessionGuard doesn't. So an empty class derived from both
SessionGuard and ChildLookupMixin should work...
Yes, that works. Feels like a hack, but it's a working hack :-) I'm
still not sure if that leaves the vhost guarded or not, and what that

Interesting. I was getting that impression, too. Also, the code of
guard looks very hairy, so I'm not surprised that replacements are
under development. If a guinea pig is needed, let me know...
I looked at the current guard code, and it seems odd. I don't see the
point of things like __session_just_started__ (particularly as it's
user-visible :-() and the fact that login/logout are represented by
separate URLs, rather than just posting back to the current URL and
reading the form data is different from other approaches I have seen.

I'll certainly do that. I'll also see if I can add any useful bits to
SCSI is not magic. There are fundamental technical reasons why it is
necessary to sacrifice a young goat to your SCSI chain now and then.
