Thanks for responding. It looks like once I get the phone, I should be able to install PureOS on to one of my Intel NUC6 boxes. Granted, a Librem Mini would probably be the best choice. Then, I should be able within my home WiFi network, to log in to the Linux box from the Librem 5 and set the PC display using the phone shell on the PC, back to the phone. All of my configuration work will be done at home anyway. Then once that is all working as expected, the last step will be to turn the wifi at the phone off, the cellular data connection at the phone on, and set up VPN and port forwarding on my router to allow the Librem 5 to get past my router and in to my home network.
I am sure that there will be some hammering on my home router to make everything work. But success at that point should be found in getting the cell phone data connection between the Librem 5 and the PC running PureOS, to work together as well as it worked using WiFi. Once that happens, I should be able to leave my WiFi network and go anywhere with the Librem 5, and still run applications from the PC in real-time, from the Librem 5. Granted, the only applications that will format well on the phone will be those that are supported by PHOSH. But with as much RAM and SSD resourcing as I can get in my home PC server, the Librem 5 should have virtually no hardware limitations that I can think of unless I need to buy a bigger home L5 app/file server.
The benefits of this configuration can be many:
1.) My data can stay safe at home where it is routinely backed up.
2.) From anywhere in the world, the phone could be used as-is, or plugged in to a big monitor/keyboard/mouse, to literally put me on to my home PC and run any PHOSH or non-PHOSH program that is installed in to the home server, and using all hardware resources of the PC with or without the desktop hardware plugged in to the L5.
3.) If the L5 is ever stolen, all the thief gets is locked-up hardware that connects to a then-blocked server.
4.) When I sit down at my home PC and login there, everything will be exactly as I left it, regardless of where I last used it from.
5.) I could install an independent opensource web-crawler search engine at home and run searches from my L5 that do not require Google or any other search provider.
6.) Email and anything else can be served right from home, where no spying or advertising will be built-in. The only customer would by myself. Any time I get tired of new forms of privacy violations, I can think of how I might move the violating service or app in to my home server. Eventually, a person could almost disappear from the information grid altogether without giving up anything to do it.
7.) The next step would be to share these resources with family members and maybe with friends. I am guessing that a properly configured server PC might support several L5 users.
