As long as the aggregate is visible, reachability is as good as for IPv4 PI space, if not better.
But note that if the most direct path filters out the /48, following /48 will result in going a "round-about" route, possibly through all kinds of 6bone-oriented experimental networks. I (and many others, no doubt) have seen packs crossing the Atlantic multiple times -- caused by some folks (e.g., longer path) allowing the /48 through, others (the shortest path) filtering it out. I wouldn't recommend advertising more specifics to anyone... and again, I consider that a feature :-) -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems.
