This is also a weak example for the point you want to make. In this case - as in the case of a web shop with no remote scripts - you're not delivering any computing via SaaSS. You're delivering a *document* generated by the software to the remote user.
IANAL but I don't think Affero copyleft would be triggered by sending such outputs, even if the document-generating software was under AGPL.
