It's interesting that this comes up now. We (a school district in MI US)
are now part way though the process of deploying about 25 boxes in our
various buildings one of the purposes for which will be a simple sharing
of "public" access space for users within a given building. Our goal was
to have no user/password overhead and security (with the term applied
loosely) is merely to limit access to the share to the network subnet
the building lives in (all of our buildings have individual subnets).
These shares are publicized as basically temporary scratch pads which
are not backed up or supported in any way other than simply being there.
In spite of that potentially transient nature they are still used heavily.
From what I saw in the rest of the thread it looks like there will
still be a way to do this but I thought I'd chime in since the subject
has come up and we do use security=share to accomplish this at present.
