I would like also to discuss the application of the latter work to parameter extraction from SNe catalogues. We indeed found that the inclusion of lensing effects in the analysis significantly changes the resulting best-fit model. For more informations please see: http://arXiv.org/abs/1002.1232 Informations about the turboGL implementation of the stochastic method are available here: http://www.turbogl.org/ The new version with the above mentioned additions and a follow-up paper will be available in September.
