Ah, thank you for linking to this paper.  It seems I was missing was the
package-management aspect provided by R2 through CRAN.  The instillation
of all software dependencies is a huge benefit exactly as installing
software with apt-get or pacman is simpler than running "./configure &&
make" and manually resolving dependencies.

While such a tool makes sense for a single language system like R, I
fear an Org-mode version of such a system would have too wide of a
scope.  Given that code blocks may contain arbitrary languages, and that
sh blocks can freely call any command-line executable such a system
would turn into a system-wide package management tool.

Perhaps there already exists a portable package management system
designed for local installs which could handle most of the heavy
lifting.

As another option, distributing Virtual Machine images are one solution
which I think work well and are increasingly realistic.  Or similarly
providing the research environment as a cloud server image (e.g., Amazon
EC2).

Certainly an interesting area for further work!

Best,
