I'm a little surprised by "If after 10 days I get no reply I will consider all of the current NetworkX code OK for relicensing and will proceed with the change." I wouldn't make changes to the Sage library copyright by mailing the devel list and giving people 10 days to assert copyright or else, since technically the onus would be on me to get permission from everybody who contributed.
