Figuring out "where" something is (and "recording" that data) is fairly
straightforward. The tough part is what friend Bush has been trying to
hammer home (and its showing up in other places as well.. provreg for
example) which is:
Who gets to know (and to what precision) which attributes about "where"
the object of desire "is"? For the properly paranoid, that means each
object of desire (OOD) needs to "know" about everything that might want
to find out "where" it is, attach a policy to it so it knows what and
how much info to release to the querier. This might be too much state to
keep.
While it may be too much to have the protocol make the presumption that
any OOD can be located to an arbitrary degree of precision, it is overkill
(IMHO) to require the OOD to keep an arbitrary number of policies about
who gets to know what and to to a given degree of precision.
Finding that middle ground will be tough. And when "rough consensus" is
reached, it will be, at best, an 80% solution; i.e. no one will like it.
