Hi Joel,


Good to hear from you.  Speaking as a lowly software developer,
I have a couple of questions about your posting:

What markets are currently out of reach (or otherwise difficult
to penetrate) due to the lack of such an interface standard?
I'm just trying to get a better understanding of this situation,
as such a statement would appear to be a major, founding premise
for commencing such a standards effort (IMHO).

Not being closely involved with hardware specifications processes,
perhaps I might be missing something here, but how can a private
venture really ensure confidentiality?


I mean, if company "A" tells the venture that feature "X" must be
in the spec--and the venture then adds feature "X" to the spec--
what keeps company "B" from saying, "Hey!  What is this all about??".
What is the venture supposed to say to company "B"?  Something like,
"Well, don't worry about it."  Or perhaps, "Sorry, but I can't tell
you anything about that."


Sounds very strange to me.  Again, perhaps this is because I have
not been closely involved with any such arrangement.  Can you say
whether this kind of arrangement has been successfully performed
in the past?  If so, can you cite the specific arrangement?


Hey, if such an arrangement really has been shown to work, then
I sure would like to see if it can be equally effective in developing
software standards.

With all due respect, that might not be quite accurate.  There was
at least one company shipping a full-blown, state-of-the-art (even
by most of today's standards) way back in 1986 or 1987.


I'm sure Mr. Jones is a fine engineer with plenty of accomplishments,
and I certainly mean no disrespect.  I just wanted to make sure the
record is not misstated.

Very interesting comments, Joel.  I personally have no problem with
the PWG starting up another project to pursue this initiative,
but that's just my opinion.


One thing to ponder, though.  When Don Wright first brought up this
concept to the mailing list, Bill Wagner immediately responded with
a tactful statement saying (in my words, now) how the printer interface
industry seemed to be doing just fine without such a standard.  Even
as a software developer, I think I accurately caught his drift...


Unfortuntely, no one else has spoken up (on either side of the fence)
since this idea was first raised.  What do other hardware vendors
think, especially the network interface card manufacturers?
