Developemnt has started right now, so there is

This is the repository where the IPP Scan extension of sane-airscan will 
go go:


Alexander Pevzner is mentoring Rishabh Arya on this project.

Rishabh, do you have any code repository to which you are uploading your 
current work?

Michael Sweet (author of CUPS and PAPPL) is mentoring Abhik Chakraborty 
on Scanner Applications (IPP Scan as a server, sandboxable scanner drivers).
Michael, Abhik, do you already have some code on this project?

IPP already has authentication methods which should not only work for 
printing but also for scanning.

Michael, could you help Bastien here?
