It seems the porn industry is warming up to Bitcoin. GadgetCoin actually started to work with the porn industry
http://bit.ly/1LDeFdL Using Bitcoin, the blockchain and smart contracts GadgetCoin offers 95% cash out for the web-cam models
http://bit.ly/1GUAH7vi don't think any altcoin would be able to provide any liquidity to a web cam business or a business model is they are not backup by btc revenue in order to keep the price stable.
That plus, models have a hard time with understanding bitcoins, let alone some coin that they have never heard of.
The main costs behind video streaming are the server, internet traffic and RTMP server licensing. GadgetNet disrupted this business model by decentralizing the streaming. Normally an RTMP server streams the video to the viewers, but in GadgetNets instance the broadcasters push the stream directly to their peers.
Very much wrong, the main cost for a webcam site, is marketing. Remember no one shows up, they don't get paid. Operating cost scale with that. Also decentralized streaming is very poor quality. People want HD, not SD at best and bad bitrates. Even p2p video is not up to the quality people want.
