WiFi deployments use ESSIDs. I'd say that one's refusal to use ESSIDs is refusal to abide to the manual, build broken things and then blame IP. > When you say visible - what do you mean?

How much would Henning pay me to build a consistent plan for FunkFeuer Netzwerk? Then I'll say. > Using a different channel and ESSID for every link? Yes, different ESSID and channel for links in proximity where there may be a risk of visibility of link layer addresses. It's like the map colouring problem - there are solutions. Internet too has different IP subnets on different links. > And even worse, consider a setting where routers actually move in an > unknown patterns (i.e. are "mobile"); how would you update ESSIDs > and channels? Does such a setting really exist (pure random movements like in Brownian)? Example? For some wireless deployments studies have been performed to identify patterns: vehicular, urban citizen, more. For each there are possible plans on which WiFi would work good. Even the most arbitrary movements like in a battlefield have a very high degree of planning - the command and control is very centralized. > Because multiple links share interfaces in a non-transitive manner > > > Well yes, at link layer level.
