Here is proposed / updated text for the -im document, to which we can point from the -chat document: This document specifies methods for exchanging "page-mode" instant messages through a gateway that translates between SIP and XMPP, and [I-D.ietf-stox-chat] specifies such methods for "session-mode" instant messaging between MSRP and XMPP. Such a gateway MUST be compliant with the minimum security requirements of the textual chat protocols for which it translates (i.e., SIP or MSRP and XMPP). The addition of gateways to the security model of instant messaging specified in [RFC2779] introduces some new risks. In particular, end-to-end security properties (especially confidentiality and integrity) between instant messaging clients that interface through a gateway can be provided only if common formats are supported. Specification of those common formats is out of scope for this document. For instant messages, it is possible to use [RFC3862] and [RFC3923], but those methods are not widely implemented. A more widely implemented albeit unstandardized method for interoperable end-to-end encryption would be Off-the-Record Messaging [OTR]. Peter
