Hello Torsten,
> - Enhance org-ruby?
I would be glad to help out in this regard. About the completeness of the implementation of the Org mode ruby parser, it would be very helpful for me to have a set of examples that describe how each one of the features of Org mode Emacs exporter should be rendered in to HTML.
I tried to do some work about this some time ago to identify the coverage of Org ruby HTML exporting compared to the Org mode Emacs exporter:
Is there a set of examples of all the features from Org mode anywhere?
By the way, recently Github has upgraded to the 0.8.1 version of the org-ruby gem, so Org mode rendering to HTML should have improved a lot (previous version they used was 0.5.3 so it took a while for them to evaluate upgrading the gem).

Until I have identified the coverage, my current approach with developing Org ruby is 'on demand', so if you find and issue please submit to the issues tracker on Github:

Cheers,
