I have been running VMWare on a Ubuntu base machine for years now. When I started using Proview I created a new Debian 8 virtual machine with a 20GByte hard drive. I just copy the 20GByte VM over to another disk to back it up and save changes. Its also a very good way to distribute Proview nodes.

Once the VM is set up and running, just copy it to another computer running VMWare and its complete.

This makes backing up computer systems very easy.

I believe distributing Proview as a VM would be a very good thing to add to the WEB site.
You could just download the small VM and start it up.

All of the hard installation is completed for you.
