P.S.: Shane, have you developed Symlinks any further? I think they could be extremely useful. I tried out the initial release and liked it, except for the fact that the symlinks looked EXACTLY like real ones, so they can be very irritating ... I'm not sure what to do with symlinks.

A way to approach how this would be useful would be to contrast different use environments for ZODB code. The same code could be used for: - Unit testing, prototyping, and general exploration could use ZODB with DemoStorage and the default Connection objects. - Production use could make use

Hi All, As someone pointed out on #zope, it is possible to view folder contents using a webdav client as an anonymous user. I.e. download cadaver (http://www.webdav.org/cadaver/), open yourzopeserver:8080 and do ls. Then decide if you want anyone to be able to access this. Eventhough hiding
