Local collaboration on two macs PLUS remote editing via parsec in realtime

A little tricky usecase:

In this project, I am working as a director and work together with an editor.

We usually do this in the same room on two computers.

I am writing the voiceover text and discuss the content, but I would like to be able to log and grab some interesting clips/bits and send them to the editors machine, so I dont have to tell him at which timecode he can find all those clips all the time. Thats a huge timesaver!

Is it better to work with "team projects" for that or just exchange an xml?

We will definitely have a copy of all source footage on both devices because I prefer to work with SSDs instead of using a shared NAS storage (with limited bandwidth) - so I guess Premiere "Productions" is not an option.

Now it gets even more complicated:

The editor isnt able to come here, so he needs to work on my "main" mac remotely in real time via parsec.

(Basically video screen sharing my desktop)

I will be able to see what he is doing in realtime and we will communicate via phone in the meantime.

As parsec needs lots of internet bandwidth I am not sure if a "premiere teams project" would cause a lot of traffic and interfere with the parsec screen transmission. Could this interfere?

And is a "team project" stored ONLY in the cloud or locally on my hard drive as well?

Will I be able to perform time machine backups of the project?

The other workflow would be to import all my footage into a project, copy it and then work in this copy on my second machine. Now I could just send xml-files via airdrop to the project he is working on. As be both have a copy of the same source footage I hope it will automatically relinked. Does this work flawlessly?

Thanks for your help!
