Using Toolkit for freelancers

We work with freelancers over the internet mostly for our projects. Is there a way we use toolkit in Photoshop for example to publish files and lunch Photoshop but on people's individual computers not connected to our own?

I really like the idea of toolkit how it keeps track of the work but it seems like it's designed for local network not people that are using toolkit with freelancers?

Do freelancers need to create directories on there own computers that match the "primary" and the Shotgun still recognizes it?

Or have people used Amazon servers has the local server and everyone access the Amazon server like it's the local server or something to this idea?

I'd love to hear from anyone that is working with this type of system I've described to hear solutions you come up with.

Thanks for your time
