[private-measurement] What parties will participate in helper party networks? (#19)

eriktaubeneck has just created a new issue for https://github.com/patcg/private-measurement:

== What parties will participate in helper party networks? ==
This issue was initially raised by @alexWhitworth on the meetings issue for [Agenda Request - IPA Status Update](https://github.com/patcg/meetings/issues/70), which essentially came down to:

> Yes, I understood everything in your comment/proposal except whom the 3 parties are, particularly as it relates to a real-world use case.

I responded that the technical proposal is intentionally abstract about this, and that this is more a policy question. So this issue is intended to start a conversation around that policy question:

**What parties will participate in _helper party networks_?**

Ultimately, we both need to:
1. Reach consensus in the PATCG around what a helper party (or, in our [Threat Model draft](https://github.com/patcg/docs-and-reports/tree/main/threat-model), an Aggregator) is, and what types of parties could be considered.
2. Find parties to form networks who the implementers (web platform vendors) will trust to uphold the assumption of non-collusion required from \1.

A notable effort in this type of area is [DivviUp](https://divviup.org/) from the [Internet Security Research Group (ISRG)](https://www.abetterinternet.org/).

In our meeting on 8/11, @chris-wood mentioned that Cloudflare may be interested in such a role. (As @martinthomson pointed out in the other thread, it would be great if @chris-wood would help qualify this more precisely.)

Also, @alexcone pointed out that it's "hard [for him] to believe that public cloud provider would turn down digital advertising compute."

It would be great to continue this discussion here, and hear from folks both about both issues above: what properties these parties should have, and what configurations of _helper party networks_ could be trusted to be non-colluding.
