Connecting Felix GoGo Shell through XMPP / Google Talk ?
I did a pretty interesting experiment (and will be useful at least to myself) connecting the Felix GoGo Shell in Apache Karaf/ServiceMix to XMPP/Google Talk Instant Messaging Protocol via Smack library. I spent almost 24 hours just for this. The results is pretty amazing though. :-)
I also spent quite some time to make ANSI colors sort of "working". It's not strictly correct, but at least it's not entirely boring.
UPDATE: The OSGi Blueprint-compatible XMPP Shell connector is available as open source with Apache License 2.0 at https://github.com/soluvas/com.soluvas.shell.xmpp
For more in-depth explanation on OSGi, I highly recommend OSGi in Action: Creating Modular Applications in Java.
