<div>You're right. These topics might be located in the future a little bit.</div>
<div> </div>
<div>However I had the chance last week to dig a little bit into the RFCs and find some ideas, which I will summarize on the wiki at https://github.com/christoph-v/spark . I will send an update, when the wiki will have been prepared for your review.</div>

<div>If there is no interest at all -> an indication would be nice to save me some unnecessary work :-)</div>

<div>Have a nice week</div>
