Sorry for the slow response. Piotr was kind enough to walk me through 
how the proposal works and it does allow for a true subscription model. 
I still have a to do to determine how much data we will be using with 
this model so I can understand how well it scales. This is a concern for 
us as we are shifting from receiving sensor updates in an "on-change" 
model to updates every second, regardless of change. There's also 
changes in the data format that's sent, which will likely make this less 
of a concern.

Thanks,
Justin
