This is different from the way that OD works now, but the questions are is it
worse, and what
will break if we do it.
Let's consider some attributes, starting with a trivial initial set...
*Accuracy:* How accurate is the data that gets retrieved?
*Reliability*: How likely is it that a query will complete successfully?
*Latency:* How long does it take for a query to complete?
*Vulnerability:* How easily/likely is it that the service can be
compromised?
*Scaling:* How well does it operate, at Internet scale?
*PSL* *Tree-Walk*
*Accuracy: * Known problematic 100%
*Reliability:* High Mixed
*Latency: * None Potentially high
*Vulnerability:* Generally none DOS
*Scaling:* Poor admin, good ops Good admin, potentially
poor ops
