Ask HN: Anybody working on personal data plumbing?

The majority of our online interactions with companies / institutions reduce to us filling out and posting forms. This is much better than doing the same thing with paper or email. But it can't be that way forever. Especially as the volume of data increases, types of data become more varied, and frequency of such interactions increases.

My vision for how it should be is more like payments. I give the company / institution my card details, and they transact against it to get what they need. This transaction is facilitated by a clever broker company (i.e. the company I want to build) who knows how to fetch the data from me - but doesn't own or control said data - at some small latency.

Why doesn't the VISA / MasterCard of personal data transactions exist yet? Is anyone working on this? Does anyone want to?

I get that this sounds a bit crazy right now, but I think this is a huge business in the next decade.
