BTW, the whole point of a GUID in the feeds is to provide an
identifier to feedreaders that uniquely identifies a post. So changing
the GUID, ever, makes no real sense.

On that note though, the GUID should be unique before it goes live on
a website. If it's using http://localhost or something, then it's
probably not unique. If, however, it's using a domain you control,
then you also have control over its uniqueness.
