I've put a preprint of a manuscript entitled "bioGUID: resolving, discovering, and minting identifiers for biodiversity informatics" online at Nature Precedings: http://hdl.handle.net/10101/npre.2009.3079.1
The manuscript covers some of the issues discussed in this thread.
Irony alert:
1. The manuscript has a handle (hdl:10101/npre.2009.3079.1) as it's GUID
2. As I write, http://precedings.nature.com is down

Rod
