I hear  point IMO the question is probably more to know until when it becomes a bottleneck ETS offers a simple way to maintain a fast concurrent access to data across processes. I believe it will takes time before achieving any bottleneck in term of concurrent accesses (do we have benches for it?) . But I like your conservative approach also. I need to think a little about it.
