Possible SES?
That's "Shit's Easy Syndrome". You obviously know way more about it than I do, but Box does do this for a living. Easy for you doesn't necessarily mean easy for him, and I don't like making promises on other people's efforts.
However ... I still say if you can prioritize it, and they can, that that's all you need to do. Automated messages always get last priority, problem solved.
Here's my assumption, by the way: Once the hardware and software is in place to do this at all (including the gateway Box mentions), I assume that the incremental cost of each message approaches zero until you reach saturation of some part of the system and have to increase capacity. Is that a valid assumption?
