how should activities handle lost network connections?

[erikb]

If a network connection is lost, there is no straightforward way for an activity to be alerted and to attempt to reconnect.

If the connection is lost, it is unclear how an activity should attempt to reconnect.

From a ui pov, the shared combobox remains insensitive throughout. Perhaps a notification could go there about the tube connection status?

I met briefly with Steven Murdoch (sjm217) who casually suggested that I begin thinking about designing an API for networking stack clients to query information about the security properties of their communications channels. That information seems somewhat related to information about the capacity, jitter, and latency of the channel. Anyway, I haven't committed to the task yet, but I'll update this ticket if anything comes of it. :)
