So far I've looked at SparseM package using the sparseMatrix data type. It's builds the 20M MovieLens into a sparse matrix very quickly, but subsequent operations are proving to be a challenge.

So far, several attempts at Pearson Correlation and they're all pretty fruitless.

Looks like moving forward with "incidence matrix" format is the way to go.
