Babak,


The main argument given to me was that a number of security concious
organizations are prohibiting the delivery of data out from their
organization e.g. via FTP, while allowing HTTP on the basis that it is
normally used to get data in from the outside, but gives out very little
data.  If we start using IPP to send out big print files, these
organizations will start getting worried and looking for a stopgap solution,
until they find a way to dig into the HTTP flow for details. A short term
solution might be to quite simply have the firewall stop the use of HTTP
altogether.
