I don't think this is the problem here - the proposal says: "Create an
add-on component that allows a Calc user to let the R environment do
calculations on data from Calc cells and put the results into the
spreadsheet again". It feels much more like embedding R in the OO
spreadsheet and/or elsewhere, which would be similar to using DCOM in
Excel. There would also be questions about how tightly integrated an
embedded R should be, how functionality would be provided and documented,
and how such a setup ought to be administered and maintained.

As RExcel, the structure depends crucially on having joint expertise in
place to write and maintain the R script glue (dialogues) to provide the
functionality being added to Calc. Typically, this would be something an
organisation of some size might need, but it would be unlikely to be a GUI
for novice R users unwilling to scale the learning curve (a steep learning
curve, of course, means learn a lot in a short time, hence a good thing!).
