This begs the question: what is too big? Currently, we consider stanza size to be somewhat unbounded, as XMPP-Core imposes no size maximum. But I believe we do need some mechanism for a stanza maximum size, otherwise XMPP software is prone to denial-of-service attacks. However, email has no maximum size, and we probably have a great many XEPs assuming an unbounded size as well. Thus, as soon as we apply a stanza size maximum (which, I'm prepared to argue, is 100% necessary), we may run into trouble with our existing protocols. I think this is something we need to discuss. -Justin
