There is no statement in the XEP that the stream in inband. The
clients can use SOCKS5 or a direct connection for the private
stream. I do not see were you want to put the body in that case.

If you use IQ stanzas for e2e streams they should never reach the
wrong resource. If they do, it is a bug in the server. And even if
they do, the receiver should rehect that IBB stanza (unknown sid) and
the sender knows that the e2e stream is broken.
