In regards to OSGi maybe it is something you would propose and help out
with for the client rewrite
https://cwiki.apache.org/confluence/display/KAFKA/Client+Rewrite I don't
know what is entailed for coding and long term support and what the
community benefit would be.  If you could help with any of that it would go
towards making it happening.
