Ever consider just submitting a talk about RingoJS to "cool marketing" AKA JSConf? We are a pretty open and "underdog-rooting" group. I might know someone up in the decision committee...
Great idea, you should probably ask Hannes (the RingoJS lead developer though)
I submitted a Ringo talk to JSConf.eu 2010, haven't heard anything back from these guys so far. If that fails, I may apply for next JSConf.us. We'll get the word out there eventually :)
