Michael, Concerning iPojo itself, I think you won't find much tutorials outside of iPojo's website. That website could definitely be improved and some pages are outdated. I know iPojo is used in various companies, but iPojo users are rather quiet compared to Guice or Spring/Blueprint users who blog a lot more.
I suggest you take at look at the examples available at https://svn.apache.org/repos/asf/felix/trunk/ipojo/examples/tutorial-maven The samples are depending on iPojo 1.5.0-SNAPSHOT so be sure to update the versions (in pom.xml files). We switched to iPojo some time ago (from DS), and it was painless as were already using Maven to build our projects. We simply had to switch annotations and add the proper Maven configuration -- and then benefit from all the other exciting features of iPojo. There is a release coming soon that will fix a few bugs so in the mean time we are following the trunk version. I suggest you take a look at iPojo's JIRA if you encounter a bug during the build in the maven-ipojo-plugin: if the bugs are marked as fix you will either have to build your own local copy of iPojo (1.9.0-SNAPSHOT) or wait for a release.
