After some struggling with CLASSPATHs and awkward type casting exceptions[1], I have successfully built my first OAA-agent! 

It's a data processor that lives in the sphinx-frontend and hands out samples (or other data, depending on where it is positioned in the frontend) to any other agent that asks[2].

Next step is to split the frontend-pipeline in two parts and connect them via OAA. On we go!

[1]: OAA-documentation does not say, that ICLList(java.utils.List args) only likes lists that contain ICLTerms...

[2]: Currently this means using oaa_shell to ask for a solution of the goal "audioData(X)"
