my two cents on the last bit:

I see ivpOf as a relation that bridges across two asserters' perspectives -- ok, not only, but when you do need such a bridge, 
that's the one. I had suggested "complement-of" as a replacement term, to denote each of   two partial views may potentially gain 
when this relation is asserted. Terminology aside, what I see here is that the rule above extends this principle, by transferring an 
assertion that belongs to X's observer, on participation, to Y's observer. Basically once you draw a bridge, a whole set of 
assertions may carry across by means of rules like this.
I just found this interesting as a way to carry knowledge across relative points of view (albeit for a limited time span)
