Here's a scenario where you can't recover state: DTMF digits being 
received from a channel. What should the application do in that case?

Ultimately this idea is formed around the assumption that all the state 
can be retrieved upon startup, so I'd scope out some use cases and see 
if that's true. Determine what state an application may need to keep and 
what can be gleamed from Asterisk. For example: do we provide a 
mechanism to know what channels are in the application, or does the 
application have to persist that themselves?

Cheers,
