Andrey has been working on the ROP version of nested contexts. I
think it is (partially?) done.

If I can answer on his behalf, Marcin is testing that right now, hence
the questions. I've updated the web site page to reflect that nested
contexts are now available.
I think it is a bug, and relating objects should be allowed between
parent/child contexts.
Not so. Parent/child relationship determines the path of the select
and commit operations, but has no effect on the rule that each
object belongs to just one context, and no relationships between
them are possible.
That's a little awkward then. If a user is in the middle of creating a
new Artist and decides to create a Painting (in a child context), then
it is troublesome to create the join. We can't move the Artist into
the child context so that it can be joined there to the Painting, so I
assume the only solution is to postpone the join until the child
context is committed back to its parent. But that is awkward since
while in the child editing context, the Painting has no access to the
Artist it should be related to.
