Lovely, welcome info forwarding, Marc.  And congratulations !!!

Impressive but ouch, Marc #2, they use overpass, and extensively.
If everybody were using their page much, overpass would soon be on their
knees.

I think that how to use POIs should be thought out before making them.
It's great how a GPS uses a selection offline and how a Web display
could do the same.
But they use predetermined kinds of POIs that they selected as data they
store locally.
May I recall another approach that I presented as a way for OSM.be to
make money.
For each "customer" or usage, a POI list is built that contains the IDs
of the OSM elements + icon URL.
The server whose task is to display the map + POIs can fetch the list
from any URL.
http://server  http://list
node/way/area ID icon_URL
...
For speed and to spare the sources, it can build a cache.

Cheers

André.
