I'm fairly ignorant about the internals of access control in
Jackrabbit, so let me go on with a naive "ideal world" idea.
I'll let others find out if that's implementable ;-)
One thing that bugs me in JCR is the lack of the "user owner" and
"group owner" concepts of unix filesystems - I find those very useful
to solve such cases. So my first suggestion would be to introduce
those concept, ideally allowing multiple groups to own a node.

Deny a (custom? new?) "list child nodes" permission on /_user to anon

Session.getNode("/_user/ieb") works because that doesn't require
calling getNodes() on /_user, so "list child nodes" permission not
needed.

For the same reason

I think you mean "only ieb", in that case I'd set "user owner=ieb" and
"only user owner can read" on /_user/ieb/private

Yes, because that doesn't require the "list child nodes" permission -
upload must only check for no conflicts with existing nodes (tricky?)

as above

Dreaming aloud hey?
I often find that's the best way to look for solutions...
