Hi Rudi, Hi all, maybe what will help us is that we are not so much interested in individual cornercases anyway. As a starter, we could focus on Field::Biology packages only. Accidental de-anonymisation would mean that one could guess who installed, say mummer, emboss, gnumed-client and bioperl at the same time for a given version number and architecture. I think that it is an acceptable risk, because the nature of this information is not very valuable.
