VirtualBox Wrapper
==================

Wrapper to provide easy to use GUI isolation[1].

Xinput and clipboard isolation
------------------------------

VirtualBox offers some protections agains inherent insecurities on X server
architecture[2] but not as tough as [Qubes](https://qubes-os.org) or maybe
how [Subgraph](https://subgraph.com/sgos/index.en.html) is planning.

It's still possible to sandbox applications using VirtualBox and have some level
of protection while having a slightly simple setup if you can't migrate to Qubes:

  1. Clipboard sharing: you can entirelly disable this feature or have just
     the hability to copy content from the VM to the host X session.

  2. Xinput isolation: by my early testings, VirtualBox provides xinput isolation
     as the guest can just capture events when the guest window is focused. But this
     needs further research.
