BitYay is going to be a market place / auction house similar to Bitmit using various crypto currency's I have also been toying with the idea of giving users the option of using paypal. 107.170.110.137 is just one of our work spaces for preview. There is still quit a bit of work to be done on Bityay.
As for cam4btc.com its been around since 2012 we are switching from rtmfp to a nginx Rtmp server. Rtmfp was only meant for p2p feeds and the video quality suffers allot when there are more than 5 watchers on a stream.
Also the design needs to be rethought and allot of other small issues need to be dealt with.
