I think some of us especially Guix-HPC folks are convinced about the
usefulness of Guix as one of the tools in the reproducible science
toolchain (that was one of the themes of my FOSDEM talk).  :-)

Now, whether Guix is the right tool to distribute data, I don=E2=80=99t kno=

Distributing large amounts of data is a job in itself, and the store
isn=E2=80=99t designed for that.  It could quickly become a bottleneck.  Th=
at=E2=80=99s
one of the reasons why the Guix Workflow Language (GWL) does not store
scientific data in the store itself.

I think data should probably be stored and distributed out-of-band using
appropriate storage mechanisms.
