Alessandra and Wahid, in the security TEG there were representatives of all the experiments and some sites. The output was presented to several GDBs, MBs, a whole day pre-GDB, and the WLCG workshop. Slightly more than running it past some other groups. The only remaining argument I hear is 'we've been talking about this for so long we can't possibly do it now'.
Regards,
John
