As I mentioned, I was writing quickly in the interests of getting tentative answers out, at the possible expense of precision and clarity. Ray has pointed out something that wasn't clear:

I.1.c. ISOC is the organizational home of the IETF (because the IETF is unincorporated, actions that require an IETF contractual relationship are handled by ISOC). Effectively, ISOC also works as a kind of bank account -- it provides the handling of most of our money, and currently provides approximately 1/3 of the IETF annual operating budget (the other 2/3 are related to meetings. ISOC handles that money, but in a pass-through manner). Apart from the ISOC members (and therefore Trustees) that ISOC appoints, and some services that ISOC provides to the Trust (like financial statements for expenses relating to the Trust), there is no formal relationship between ISOC and the Trust.
There _is_ a formal relationship, which was supposed to be included in the "and some services that ISOC provides to the Trust", but anyone not intimately familiar with the way my brain organizes things might not have understood that :) The Trust has a services agreement with ISOC for certain services. This is something that came into effect quite recently as part of the additional formalization that I mentioned we were undertaking to ensure we're in a position to take on this new IPR. The adoption of this policy is minuted in http://trustee.ietf.org/documents/IETF-Trust-2016-06-16Minutes.pdf. We normally publish materials on the web site, but I don't find this yet. I might have missed it or it may yet be embargoed for some technical reason, but I'd expect the agreement to be published in due time in keeping with the transparency traditions of the IETF.
