In terms of routing, the main issues are: - There must be a small-world network. Clearly random automatically selected participants will not form a small-world network, but acquaintances probably do. I repeat, randomly selected people through any automated mechanism WILL BREAK ROUTING! - There must be enough of them online at a time that there is a viable, routable network. In terms of security: - Darknet is much more secure than opennet simply because the cost of getting a connection to the target node is much higher. This greatly reduces the effectiveness of mobile-attacker source tracing attacks, one of the most serious known attacks. - Clearly you are vulnerable to your peers. But no more so on darknet than on opennet, really. On opennet, it is possible to get many connections to the target; on darknet, you have to persuade the user to give you such connections by e.g. pretending to be many people. So IMHO unless you have serious security requirements there is no reason not to connect to acquaintances. > > The wikipedia entry suggests that specialized academic interest groups are in > the size of 150 individuals.

I don't know.
