One of the core ideas of the Silktorrent is that the Silktorrent applications must assume that the location of the tar-file can not be concluded from its name. Silktorrent applications ask for tar-files from agents, who might not have the asked tar-file available and the agents might not even be able to retrieve the asked tar-file.
