Hi!

I'd like to start a discussion how to move forward with libzypp for 11.0.

Here is the list of possible improvements I'm aware of:

- User interface
  Work on design, usability of YaST the package management frontends.
  
- Application layer
  Applications using libzypp duplicate a lot of code which should be
  refactored into an application layer on top of zypp.

- PackageKit
  PackageKit, building upon PolicyKit, allows to assign specific
  (administrative) rights in regards to software management.   

- New SAT solver 
  A new approach to dependency solving seems to overcome the
  limitations of the current solver, while
  implementing most of the requested features.
  (see http://idea.opensuse.org/content/ideas/fast-installation-tool)
  
- Build service integration
  Client-side software management should be integrated with build
  service functionality in order to support online search and
  on-demand information like ratings and screenshots.
  
- Redesign of the caches
  This comprises the SOLV files and way to store the additional data 
  to be retrieved on-demand, etc.

- zypper improvements
  There is quite some work left to improve zypper, fix the bugs and fill the 
gaps.

- callbacks cleanup
  The annoying YaST popups are a direct consequence of the complicated 
callback system of libzypp. A redesign and cleanup of the callbacks should 
give much better user experience, like 

- switch to use librpm directly for installing packages
  So far, libzypp  calls rpm for every installation of a package, instead of 
going directly to librpm

- commit part refactoring
  This is mostly about providing parallel download of packages and also 
installing more than one package per transaction. Another related feature is 
to keep the downloaded packages available on the disk.

- locking storing and application API
 10.3  allows user to configure locking using /etc/zypp/locks file, however, 
there is no GUI to do this.

I believe there is more... I've tried to concentrate on larger blocks, not 
individual features. Anyway, feel free to add more.

So, comments on the list above? any preferences? Any technical issues why the 
particular part is not feasible, or not feasible for 11.0?
