Syndie also lets your community take whatever steps are necessary to
compartmentalize your organization, limiting the exposure from any individual
leaks - for instance, one group of users could use Syndie through a shared
wiki, while another group uses Syndie through a mailing list, a third group
uses Syndie through Freenet, and a fourth group through Gnutella, and as long
as one member of each knew about one of the other group's resources, everyone
can talk to each other.
