A proxy for Instant Webcam (or any other MPEG stream) that broadcasts the websocket message from one source to multiple clients.
Install a current version of Go: http://golang.org/doc/install
Get the webcamproxy package and install it:
go get github.com/chlu/webcamproxy
Start the proxy by pointing it to the IP address of the webcam stream:
webcamproxy -webcam="192.168.1.2"
Access the webcam interface on http://localhost:8080/ to see the output of the webcam.
