Well, I guess I am going to hack off the IETF people but...

-- warning -- highly opinionated and caustic verbiage ahead

LPR is not a standard.  LPR is not as widely deployed 
as many other protocols (pick Novell's PSERVER or RPRINTER
or NetBEUI/SMB which are much more widely deployed) yet we 
are making no effort to be compatible with those.  I think the
request is unreasonable.  If a vendor wants to have a
print server that supports both IPP and LPR as an inbound
print mechanism -- great!  But to saddle IPP with LPR is 
simply not reasonable.

Is HTTP compatible with FTP? -- no, but both transfer files.
Why didn't the IETF require HTTP to be backwards
compatible with FTP -- because the work was done outside
of the IETF and finally endorsed when HTTP was so widely
deployed it could not be ignored.  I don't believe there is a 
hard precedent that has been set that says every new 
solution must be compatible with an older means used to 
do something similar.  Perhaps we should do the work and
deploy it into the market outside of the IETF's domain?

-- well, I said it and I bet a number of others feel the same way.
Any one else want to chime in?

The IESG met earlier today and discussed the IPP charter. It decided
to approve the working group once the following changes are made to
the charter:

+ The WG has to make recommendations as to how to acheive reasonable
  compatibility between ipp and lpr.  IESG understands that lpr is 
  insufficient in its current form and basically non-extensible, that 
  its behavior varies widely between implementations and so does not
  produce repeatable results, and that it lacks the security needed 
  for printing in a global Internet.  However, IESG also recognizes 
  that lpr is widely deployed, and that a new protocol -- even a much
  better one -- could be disruptive to the installed base. 

+ There is a new requirement that all working group charters
  explicitly address security, so we need to add this. 

Just to be clear: the working group has been approved, but I have to
show that these things have been incorporated to the charter before
the group is formally created.  So I'll add a paragraph or two to the
charter that reflects what IESG agreed to, and run it by the IPP
chairs before giving it to the IESG Executive Director.

IPP is tentatively scheduled for Tuesday at 9:00 am.
