In regard to using PDF as the data format for IPPFAX, I remember someone raising the concern that the data format is not very streamable. According  to the spec (section 5.17) an incremental update at the very end of a big PDF file can change the way the first page is rendered. Is this still a concern of the group? This would be an issue for small-footprint implementations of IPPFAX. Can the IPPFAX spec be written to expressly require or forbid certain features of PDF?

Hi John, 
Yes, the IPPFAX spec can expressly require or forbid certain PDF features. In particular (I sincerely hope), IPPFAX can specifically cite and require (for minimum conformance) exactly ONE of the profiles of PDF in the ISO PDF/X standards. That way we get a stable/tested profile from the pre-press industry.

Does anyone know whether one of the ISO PDF/X standards rules out the PDF construct that causes the streaming problem? If no one responds to the reflector, be sure to ask the Adobe representative at the meeting.
