Hi Boyd, Scott, Jp!

Some comments:

static zypp::ZYpp::Ptr
get_zypp ()

The zypp pointer automatically creates the library so you dont need to track 
it in another ptr, you can use getZYpp all the time.

The target is excplitly initialized, so you can delay that till t is needed 
(because it reads gpg keys and basic rpm startup (not reading packages 
anyway))

I also see you use the sqlite database directly :-)
if (sqlite3_open("/var/cache/zypp/zypp.db", &db) != 0) {

That will not give you the installed packages, except if you do itand I did 
not reailze how?

Also, I would name the backend openSUSE (ZYpp); Novell (ZYpp), or SUSE (ZYpp) 
because the ZYpp name alone is not that clear? (may be I am wrong?)

Sure

Look at:
http://svn.opensuse.org/svn/zypp/trunk/zypper/src/zypper-repo-callbacks.h

The most important there is
struct RepoReportReceiver  : public 
zypp::callback::ReceiveReport<zypp::repo::RepoReport>

You define your class implementing reporting, and then instanciate it and use 
_repoReport.connect(); and dsconenct() to enable or disable them.

There are also rpm callbacks:
http://svn.opensuse.org/svn/zypp/trunk/zypper/src/zypper-rpm-callbacks.h

signature and checksums callbacks:
http://svn.opensuse.org/svn/zypp/trunk/zypper/src/zypper-keyring-callbacks.h

and media access callbacks:
http://svn.opensuse.org/svn/zypp/trunk/zypper/src/zypper-media-callbacks.h

If there are more questions, just ask! :-)

Thanks for such cool stuff

Duncan
