This is what GUIDs/UUIDs were designed for, and they're used broadly. 
They're standardized in ISO 11578 [1], although there's a very similar 
public description in an expired Internet Draft [2]. Microsoft also 
publishes a description of how they generate their GUIDs, but I can't find 
it right now.

PS - I'm looking for a full-time job. My resume is at 
http://www.dierks.org/tim/resume.html . Looking for architecture or 
technical management jobs; I'm in New York, NY, but I am willing to relocate.
