It looks to me like Citrix is a company, not a program. Which program is it?
If it's something that allows her to access a desktop remotely, maybe she
could use VNC? Depends on her employer's policy, too.

Running DOS programs in DOSBox still runs those programs' code, so if that
code is proprietary, you're obviously running proprietary software.
Personally, I'd recommend you show them some libre games. Trisquel has some,
and there's also the Libre Game Wiki:
