Sounds good to me. Solve the end-user problems, since they don't have the ability or care to do it themselves and doing so manually has too much latency and doesn't scale.

Subject: ISP data collection from home routers 

Hello there, 

Several years ago, a friend of mine was working for a large telco and 
his job was to detect which clients had the worst networking experience. 

To do that, the telco had this hadoop cluster, where it collected _tons_ 
of data from home users routers, and his job was to use ML to tell the 
signal from the noise. 

I remember seeing a sample csv from this data, which contained 
_thousands_ of data fields (features) from each client. 

I was _shocked_ by the amount of (meta)data they are able to pull from 
home routers. These even included your wifi network name _and_ password! 
(it's been several years since then). 

And home users are _completely_ unaware of this. 

So my question to you folks is: 

- What's the policy regulations on this? I don't remember the features 
(thousands) but I'm pretty sure you could some profiling with it. 

- Is anyone aware of any public discussion on this? I have never seen it.
