Consult the free online SWIFT service to obtain the name and address of a

In theory one request could be stripped, but the SWIFT terms of use prevent
automated usage, so user like behavior is required.
Update January 2012: Always return None, as the SWIFT page to retrieve the
information does no longer exist.
If demand exists, maybe bite the bullet and integrate with a paid web
service such as http://www.iban-rechner.de.
lp914922 additionally suggests to make online lookup optional.
