There's no good way to get that data: podcasts are RSS feeds. You see IPs and user agents. How do they know who's a 30 year old male making $70,000? You an try to match IPs with advertising databases, but good luck getting any sort of real signal out of that. That data is all inferred anyway. Hell, I bet my cell phone has two dozen IPs over the course of an average day as I connect to various wifi networks and Fi switches carriers.
As it damn well should be.
That said, it's only a matter of time before carriers start tracking and selling this data.
