Hey guys, I'm Dan Shipper one of the co-founders of Firefly. Just to answer a few likely questions:

1. It's download free because it runs completely in the browser with Javascript

2. We're differentiated from other similar services like GoInstant because GoInstant has a completely enterprise strategy. They're not self-serve and they work with big companies. We're tackling the lower end of the market.

3. We're helping to solve the distribution problem inherent to marketing to SMBs with a screensharing API. The API basically turns us into a Twilio for screensharing meaning that anyone can introduce our screensharing technology into their customer support apps with just a few lines of code.

Any feedback about the product you have would be incredibly helpful. Thanks!
