Chris Palmer and myself are the primary people on the EFF side, and Jake 
has been very helpful in assisting in the first round of patches. I 
can't speak for either of them, but I'm not at all worried about 
appropriate recognition---really anything is fine. Much more important 
is having a good relationship with you and the Pidgin team so we can 
work together for this and future security-related patches.
