At Scribma, we're building a new tool for doing exactly this: sharing both code, terminal, and browser, and collaborating using 100 times less bandwidth than you would via traditional screen sharing tools.
Also, it's automatically recorded, so you don't have to worry about doing screen recording via e.g. QuickTime while coding (which at least makes my mac fan go nuts after a few minutes).
You can check out a video of it here: https://www.youtube.com/watch?v=Rsorl3-TjdY
We're on the lookout for more beta testers, so I'd love to set up a chat with you.
Interested?
If so, let me know at per@scrimba.com
