Not really.  The pathalias software assumes a DEAD cost on an undeclared
return path.  The future map entries for 'att' will not include an explicit
listing of external sites.  This will cause the return path (i.e., the
path from 'att' to an external site) to appear DEAD, which will prevent
through-routing.  The forward path INTO AT&T, on the other hand, should
be declared as normal cost, since we want traffic destined for an AT&T
machine to reach via the most efficient route.
