Sure, someone helped me setting up a script to share the wl socket between namespaces so I can run GUI programs in isolated namespaces, and if you look at this post you can check the namespaced-openvpn; also check vole’s answer if you want to run GUI programs

Thank you for summarizing it up

I’ve been using network namespaces in Linux where each one also use a different user; this way you can have multiple profiles of apps separated not only by permissions but also by the VPN connection that is the only route out

So you can have a connection that will supply your favorite iso sharer, a VPN connection to work, all unaware of each ot

I still haven’t figured how to make GUI media applications work on them though
