I'm working to create a package that allows multiple computers to stream their webcam to other computers while receiving others' stream as well.

Any idea how to implement this on ROS? Help is surely appreciated.

Use regular pub-sub? Distributing data across multiple hosts is what is was created for, I would think.

ROS FAQ on Networking is the place where you can start

Look into gstreamer in combination with OpenCV. Gstreamer allows various encoding options too (H264 compression for example) . Here is an video example of someone doing this with ROS. I hope that this helps.

Is there supposed to be a link to a video in your answer? - I don't see one. There exists gscam as gstreamer-ros adapter btw.
