I could see the IFX group proposing extensions or revisions to IPP, actually -- for example a mechanism to indicate This Is a Fax and should contain timestamps. I wouldn't want such extensions to be out of scope. > The WG will not propose any revisions or extensions to IETF Internet Fax > standards [RFC2305] and its successors. > > The group will take note of other areas within the IETF that may have direct > bearing on IPP and FAX interworking. > > Relevant areas include: > > - Security, Authentication and Encryption (SSL3 -TLS) > - Sender Identification (vCard) Conneg? > The working group will take note of quality of service issues. On the Internet, "Quality of Service" has distinct meaning -- be careful here. QoS usually means bounded delay of packet delivery -- much different from what you mean (which is likely bounded delay of the physical output). Perhaps something like: "The WG will attempt to provide mechanisms to allow interoperable implementations to be created which closely emulate the existing end-user- expected functionality of fax." but shorter-winded.
