That would be great, I looked already to the code base in the plug-in
directory and it seems you use this call to get the clustering results:
controller.query("lingo-nmf-km-3", "pseudo-query", requestParams);
am I right ?
anyway, I want to have the type of algorithm used for clustering, picked up
from the xml file, it should be easy to do so.
Any guidelines, ideas are welcomed.

That's the spirit, and is going to get better ;-).
