Good point. I had not considered that, not being in a teaching
environment. Running on a laptop, I always have a known machine with me,
even when doing presentations in front of a group/audience.

No disagreement if there is a specific need for this. Where that need is
present, this is a better solution than using the Linux native libEMF
functionality, which is problematic as has been discussed in those same
threads.
I was more focused (and confused) on the Rgui.exe menus as the principal
justification for taking this approach, but again, perhaps I am lacking
context.
