Take it a step further: Firefox could allow websites to open sockets and toss arbitrary packets around, and choose not to. If that capacity were available then Javascript could be harnessed to support all sorts of protocols and services. They could even provide Javascript access to monitoring network access point availability and connectivity management.
Imagine then a single page app you could share as an attachment through $messageService and it has all the stuff built in to create ad-hoc real networks in large gatherings that provide data resiliency against the dropping of nodes. You could have the cellular network shut down, protestors arrested, their phones taken, and the data they gathered still retained so long as any node managed to exit the area or the network itself expanded beyond the area of contention.
