Not, it should be noted, End-to-end Encryption :)
It would seem, according to another comment in this thread, as if the bridges and platform have de-facto access to all traffic unless another layer of encryption is performed.
Apart from some vague notions to 256 bit and SSL there is very little written about the security and threat model of the network.
Unless I am also reading the marketing wrong, this also seems to be positioning itself as a new communication network - completely centralized to a single company/organization - with no published standards. Compared to wifi, bluetooth and to an extent the mobile network - I can't see a winning use case for this.
