You may want to consider using Google's Fusion Tables for this. Their map view will generate heat maps out of millions of points quite quickly. Plus, you could easily add a selection to narrow the maps down by user. I don't think you need to display Fusion Tables tiles in their API, either. Technically it's easy to add to OpenLayers but their terms might say otherwise.
