The job control data set should be something like a JDF job ticket at 
best, or at least a string of key=value option settings. For the former 
we should implement the JTAPI ASAP.

On the Cairo Summit was only discussed about adding a function to insert 
arbitrary meta data into a PDF file generated by Cairo. How the job data 
looks like we have to determine.

The current PDF workflow requires the option settings to be submitted 
separately from the job data, for CUPS as IPP attributes. On some 
network printing protocols, like SMB or LPD this is not possible.

See above, we should implement JTAPI for that.

This is mostly done. What is needed is;

  - A secure package signing concept, so that the distributions include
    the key for authenticating our binary packages. This we should do
    ASAP. We need to settle an agreement with at least SUSE, Red Hat, and
    Ubuntu.

Here we must see whether all our concepts really work as intended, but 
also see whether applications do printing the right way (using CUPS 
APIs, CPD, present PPD options, produce correct PostScript/PDF, ...)

Due to lack of manpower none of our LSB 4.0 proposals was taken into 
LSB. So simply go back to zero and re-propose them for 4.1. This time we 
need to find someone to implement test suites and to write specs 
(printer manufacturer?).

Windows and Mac support it on OS level AFAIK, Linux should support it, 
too. See recent discussion on OpenICC mailing list.
