If the streaming application for remote access is able to stream the audio and video being edited at high fidelity, then that;s a pretty big deal. I havent tried Jump Desktop yet, but if it really can do that then thats huge props.

Setting that aside, you do still need a machine with the specs to stream the audio and video at as close to lossless quality as you can, so something as shitty as a chromebook probably wouldnt actually be good enough, it's CPU and NAT might not quite be up to the job to stream 4k resolution video lossless.

But you also dont need a super powerful laptop either. Probably something in the ~$800 range would be sufficient, which is still magnitudes cheaper than the rig you'd need to edit the data locally of course.

So I think it's still awesome if it really does work, I am hugely in favor of VPNing into a centralized server for performing editing work, allowing editors to access files lightning fast (because instead of access them over network, the drives are right there directly connect to your server, so you're effectively doing work on a machine with potentially petabytes of storage capacity!)
