What would be the coolest way to zoom? I thought of a slippy

Others mentioned presets like continent/country.
I could also imagine to let you set an arbitrary bounding box
based on a zoom level.
eg you say you want to see zoom level 13 and then you get a
bounding box that you can place over the area of interest.
Coolest would definitely be transparent tiles, as it's the most
versatile. You (or others) could then implement presets for
countries/states, take advantage of OpenLayers shift+click+drag
zoom functionality, etc.
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.
What about OpenLayer clusters
