yes.  I think we are in sync here.

On to inventory (and asset storage)

yes, again. I had in my mind the concept of "home sim" - the place where you
are "registered". (could be a field in the certificate, or such). Then in
the simplest case we could have the assets stored either within the same sim
(to allow the plug-and-play operation for the majority of the users, who do
not have a lot of registrations on their sim anyway) - or to allow direct
reference onto a separate server, which would store the assets, with the
"home sim" possibly being a commercial entity providing this as a hosting
service to their users.

Everyone should have at least their own inventory stored locally. Whether or
not this would be backed by a DHT is another story. In the ideal world, yes,
something like GLACIER ( http://epostmail.org/technical.html) might be nice
(it claims the 6-nines availability in the case of 60% correlated node
failure) - but this would be also a rather slow media, so the biggest reason
to use it as a "distributed backup" - you reinstall the sim, and assuming
that you have kept your private key/cert pair, then you can suck all of your
data back in upon the restart.
