I dont think anyone wants to ignore volume products.. but the work is
centered on Quality Document Distribution above and beyond what is
currently available. I have not included a requirement for low cost
implementation..is this what you are suggesting? You should note that any
IPP implementation on a device will entail a significant cost well above
the $200 price point due to the necessity for keyboard, network connections

You missed my point.. if the IPP client is a "network scanning terminal"
(DUH .fax like device) .. we can safely assume that people will fill in the
little cover sheets.. however if the IPP client is software ..yes then we
can make recommendations on how that client should behave.

The the discussion in the FAX WG centered on the issue of cover pages
through gateways to the PSTN. Not a end point to end point SMTP transaction.

They usually are, but they are necessary and currently have a legal basis
on the GSTN. You get your lawyers and I'll get mine ....:-) but we can
offer some limited umbrella to the protocol if we attempt to conform to
current legal requirements. There is come case law on this as well that the
transaction is protected, irrespective of the underlying transport, if it
has shown to attempt conformity with existing law. In other words... I
would have a great case to sue a IPP spammer under the "junk fax" law if we
state our goals well. We can extend the protection of 47 USC 227 to IPP
transactions. That I submit is a useful goal.

The United States Federal Communication Commission
regulations and US Federal Law (47 USC 227) state:


"Identification Required on Fax Messages

The FCC's rules require that any message sent to a fax
machine must clearly mark on the first page or on each page
of the message:
* the date and time the transmission is sent;
* the identity of the sender; and
* the telephone number of the sender or of the sending fax

In the general case maybe but ...
Not true in many Judicial Districts (California, Wyoming etc) where there
are specific rules on fax that do not apply to e mail transactions etc.
also GSA rules on bid submissions etc.

Please state your position clearly ... we are not talking about existing
GSTN fax machines here. You seem to imply that this work only has value if
the device implementing our new work has a low Bill of Materials cost?

Its really not helpful to continue to insist on goals based on the need to
support 8 bit controllers. Some vendors are interested in adding value
(read margins) to their products and if the ultimately agreed to mandated
features require more sophisticated hardware components .. so be it.

So you are saying that the goals must reflect some LCD hardware platform?

Great .. but you realize that other file format support may require much
more sophisticated hardware. Color?

The whole notion of receipt is that both recipient and sender can log
transactions and/or output some transaction response. Like the little slip
of paper thermal fax machines spit out now or the weekly transaction
reports that higher end departmental devices can produce.

This is what we are talking about. We OK here ?? Rough Consensus? :-)

But remember those high end IPP machines are not required to do some of the
things that we propose like maintain transaction logs with time/date
stamps. The functionality we propose offers the options to them as well.
IPP was designed as a distributed printing protocol not really as a
document transmission service. I know that seems like a Politically Correct
distinction but it means a great deal in the context of what we propose.

Yea I know .. SRP looks like $149.00 with superstore distribution. I've run
these numbers myself. Been there done that.

At the price points YOU want!!

But I submit that the introduction of any new technology like this
traditionally begins with higher end devices and works its way down the
price point scale as components become less expensive and more integrated.

This has been the pattern for the whole PC industry .. not to mention the
fax machine industry.

Oh I think when we dive into this you'll see that we're not too far off.
High end machine vendors will support color TIFF, PDF ..maybe
certificates. And I suspect they will support RFC 2305 (t.37) as well. The
notion IMHO is that we have needed a Store and Forward as well as a point
to point oriented protocol.

I hope you are right .. but don't forget there are some really serious
