Well the biggest problem I've run into in the screen cast is that os command: 's underlying primitive  blocks the VM execution. So while demoing using curl from inside the VM, my clever fork a process code still requires detaching the shell process producing a sad race condition. 

Funnily enough the harder example of making the HTTP request using raw sockets works fine. 

I am going to capture a few minutes of more programming and debugging, but my B roll is now about 2 hours long.  I had a couple VM lockups too so it took nearly 4 hours to shoot a good 20 minutes of video. 

I actually shot the writing of all of the code, so I will make the images available. I haven't had much success filing out this particular module as every time the transporter runs my image locks up. And the app goes spinning wheel of death.
