Does anyone have robust code to generate globally unique IDs which won't break XML parsing,
and work on several platforms?
I was thinking of using an entropy pool to seed a cryptographic PRNG, used to generate a sequence of SHA-1 hashes, dumped to an XML-armored representation.
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.
