I don't think this will work out in the general case.  Some devices have 
properties which can be used for that, i.e. network cards have a mac 
address (no attribute yet but I expect it will come some day).  Not 
every device class has specific properties you can use to identify them 
though.  How would you identify a sound card for example?

Hmm, good point.  How about using a bitmap then?
