Tor ( up ) As with I2P, Tor is a low latency anonymizing network, and Tor's
requirements and capabilities have been kept in mind so as to allow Syndie to
operate on top of Tor as well. Freenet ( up ) Freenet is an anonymizing distributed data cache whose features complement
Syndie as well. Inserting a Syndie archive into Freenet is not a problem, and
syndicating off Freenet SSK or USK keys is trivial, given Freenet's HTTP
interface.
