There has not been a summit before, but the usual process at workshops, meetings, and in online discussions goes like this:
1) Here are the stats on women in open source (very low %)
1a) disbelief! denial!
2) Here are reasons why women say that they don't get involved
2a) that can't be right! what would they know?
3) Here are some things women suggest might change that
3a) your expectations that we be respectful are ridiculous and unworkable
4) Silence, forgetfulness, and another round of the all the above the next year.
