I support Scott's view. Let's keep moving down the path we are on -- get the
protocol right,
then do whatever mappings we think are appropriate as a second step. I don;t
think that we
could standardize on the Microsoft approach because they are passing Microsoft
internal
data structures around.

I think that we should keep with the name IPP and keep it as simple as
possible. The print protocol (semantics and operations) should basically
be the same across all mappings on transports. In other words there
could be a mapping of IPP on:

1. HTTP 1.0 POST
2. HTTP 1.1 POST (taking advantage of new 1.1 underlying features)
3. HTTP 1.x extended methods
4. Raw TCP
5. Internet RPCs
6. IIOP
7. etc, etc.

In other words, lets not create two things, but one thing. Call it IPP. Then
as Randy and you have pointed out in later (than this) emails, propose
multiple "mapping documents".

I am still in favor of #1 above (HTTP 1.0 POST) or protoptyping and
reasonable first step deployment. Maybe we will learn more as we go
through the first step which will make additional choices more clear.
