I am following the Celix efforts with interest, but I am also more 
interested in C++.

In my opinion, Celix could try to reach out to other projects and their 
(probably small) community implementing a OSGi - like environment. If 
efforts could be concentrate, or some kind of interoperability be 
achieved, this would be awesome. Projects in my mind are Poco 
(commercial), SOF, and CTK.

I tried to start some discussions about that a while ago, but 
unfortunately did not get any replies:

>>> Agreed. The Incubator PMC in particular is interested in learning how the community
intends to address the issues that prevent a podling from graduating. They feel that, especially
after being in the incubator for over a year, a graduation plan should be drafted.

help people who want to take a look at Celix, the main issue that needs to be addressed is
the size and diversity of the community.

>>>   From a use case point of view, I think we could explore the scenario where
you have Java application that uses native code. Mostly, this is now done using JNI which
has the downside that it can take the whole JVM down if something goes wrong in the native
code. From a robustness point of view, this is unacceptable, and I think Celix can be used
to provide a better implementation. With this use case, we can target any Java project that
uses native libraries, which in turn might help growing our community. Such use cases are
probably interesting enough to write about on all kinds of Java sites.
