This is a really interesting thread. As Richard notes, all these methods are "fuzzy", but all are useful; a combination should be pretty definitive. One more approach: set something distinctive for each guest -- a printer at address FFFF, a specific accounting code, etc. -- and use that (subject to other site restrictions, of course). Or do the same for non-Linux guests and divine by elimination...
