Hi Avri,
something like that should work.
My major concern is what is being used as a motivation or primary focus, which IMHO is a political issue that the proposed summit will not contribute much to solve, unless the participants have a lot of lobbying power ($$) in the US Congress.
Are people willing to talk openly about the vast number of issues related to this topic like the big firewall of China, or repressive regimes that target bloggers, or shutting down Internet services to avoid people getting organized, or government officials (as it happened in Brazil) snooping on the communication of their political opposition, or online persecution in Russia of LBGT organizations and supporters, or how some governments let criminal organizations to conduct nefarious business like the exchange of child pornography ?, and so on, then we can add the NSA surveillance as one more topic to discuss, not THE topic.
Failing to see the big picture will make this summit just a show of political attitudes against the subject of Internet control by the Evil Empire (ie the USG)
