Embolded part of my original post does not imply I think GUID is especially untrustworthy, but if there are very demanding specs I'd trust a DB based ID generating mechanism more.
But, to be safe, the table issuing Ids would need to be locked on each request. That means multiple requests would essentially be handled in a serial fashion - bit of a bottle neck on a web server ?
