Just a thought: Security, workspaces and isolated/restricted processes

I am working on an implementation of sandboxed workspaces for Xfce for a
study, based on Firejail, I'm running and it's somewhat functional. I am
not sharing it yet because I intend to recruit people here and elsewhere to
test it (in a scientific study setting), so I need people not to play with
Now there are a couple of reasons why this code is very unlikely to ever be
released as an official Xfce product:
1. it requires changes to about 20 different Xfce / GNOME apps (and in
particular complexifies xfwm4 code a lot which is a big no-no)
2. it requires in-depth changes to Firejail, making my Firejail and the
official one relatively different products, meaning I'd have to maintain a
3. it requires GLib API changes (oops! yes this is more or less
4. it only works for Linux! There is no way on earth me or other devs
here or in the Linux sandboxing community bring sandboxing to the BSDs.
5. the code, ugh, it's so ugly. When you write for academia you're
concerned about speed, and there are some bits that I just don't want
people to run without me on their back watching out for crashes.
6. I'm late on my PhD. I provide the code to my participants for
research, primarily. I don't have time to release and maintain stuff (but
it'll be fully available once the research is published at least :-) )
