How is that simple?

How is centralizing id creation "low-cost"?

What is "high frequency object creation"? 1 per second? 10? 100? 1000?
A million? Per clients? Is that for a PIM or a telecom switch? How is
centralization going to help?
"One of the main reasons for using UUIDs is that no centralized
authority is required to administer them (beyond the one that
allocates IEEE 802.1 node identifiers). As a result, generation on
demand can be completely automated, and they can be used for a wide
variety of purposes. The UUID generation algorithm described here
supports very high allocation rates: 10 million per second per
machine if you need it, so that they could even be used as

What is the scope of your schema? One client, one server? Many clients,
one server? Many clients, many servers? Is the system centralized or
not? To which extend? Is the osa foundation going to run an ultimate
object id issuance authority?
