Well, the DCE UUID algorithm uses the NIC's MAC address, which is independent of the host name; host names tend to change, MAC addresses tend not to. The UUID algorithm also includes a guard against backward-moving clocks.

If this becomes a serious problem, we can revisit this, but there are some different goals involved here. Also, a MAC address is not portably accessible across all platforms for Python, so we'd have to develop yet another extension of questionable value to its intended goal. Once we have a few hundred million Zope users, we can see if we have any real collision domain.
