Ok, to implement via option #2:
Set the following security declarations:
__roles__ = ()
security = ClassSecurityInfo()
This allows public access to the 'id', 'meta_type', and 'title', but
disallows access to all other properties such as 'ctime'.
Alternatively, you can also specify an inaccessible property with
'ctime':0 in the security.setDefaultAccess() call.
Its a bit of a hoop jumping lesson, but it works. Thanks Chris!
