Maybe I've missed the point somewhere, but what does this give you that you can't already do with Foaf? And if you really have to have this information in a feed, Foaf in RSS 1.0 fits the bill quite nicely does it not? Atom might do this too if and when they stop running around in circles, I wonder if they are regretting throwing out RDF yet...
