Bangani kentum forms

Dear all (esp. Jens, Miguel and Piotr),
What is the latest on the interpretation on the validity on the Bangani
kentum forms? I have been able to follow the story up to including Zollers
unpublished response www.sai.uni-heidelberg.de/abt/MIND/zoller/Bangani.doc
and the fact that Anvita Abbi and her students could substantiate Zoller's
original findings incl. dOkru, gOsti, and lOktO (preliminary 1998).

thanks,

Harald
