The value is that common scan frontends (simple-scan, X-Sane, scan 
functionality of LibreOffice, ...) can be used with IPP scanners.

And I do not see where this would benefit from a GSoC project.

Are the standard ready for use? Is it only the manufacturers not 
adopting them? If the standard is ready and at least one somewhat 
available device on the market it should already be enough for a GSoC 
project (at least if there is a good chance of wide adoption in the near 
future).

This looks like some of the boring thingies which one can get only done 
if one pays someone for it. And if one is not able to find students to 
make a Common Print Dialog then one will never, ever find one for this.

This is what could perhaps make up a project, like "Extend 
system-config-printer to poll printer capabilities and features via IPP 
based on IPP JPS3)".

OK, you could also talk about the GSoC as possible implementation 
platform for standards on the meeting.
