It is a valid configuration in Samba 3.0 to have multiple 'PDC' servers,
one per netbios scope.  If you are willing to separate your netbios
scopes into each location, eg with a WINS server per location (and use
the DNS fallback in windows or your WINS sever for inter-site names)
then this is a good option.  Otherwise, the PDC must be accessible from
each location.
