[LAU] [RFC] A “poor man’s”, yet professional level studio setup

As someone who has worked with and was in the Linux Laptop Orchestra for 
over 6 years, I had to bring this up: I wrote the software 
infrastructure for Dan Tramte's 
<https://www.youtube.com/watch?v=8WWrGLy7Z30>Woman Technologist Shifty 
Eyes <https://www.youtube.com/watch?v=8WWrGLy7Z30> and we used jack 
transport over local Ethernet to sync video with xjadeo on that piece. 
Believe it or not, it works! With the Linux Laptop Orchestra, there is a 
main Ethernet switch that every computer plugs into, so if you go that 
route I would definitely use one. Even a small one would help.

I can't say we ran into any major problems with doing jack transport 
over the local network, and everything remained in sync. There is a big 
however though: every laptop in the orchestra is the same model and has 
the same components. So, maybe it wouldn't work so well if the computers 
were all different models. I'm not sure. If you have any questions about 
how that worked, definitely send me an email. I worked on and wrote my 
own piece <https://youtu.be/s6-g1r1bqe8> for the Linux Laptop Orchestra 
as well that synced the computers together using pd-l2ork. Reach out if 
you have any questions on how the orchestra works!
