For a live system, it might be possible to stuff the required binaries
into a separate private directory and then just adapt the PATH
variable of the executing process to include this separate directory
without putting it in the system-wide PATH.  preview-latex by now does
something like that with most of its installations for preview.sty, in
order not to have to resolve conflicts and installations and whatever
with a preview.sty in the system tree.
