Why does it have to be online? You can use a downloaded version.

Each rendering engine which wanted that data would need its own copy
of that database. Yes. Better (or at worst equivalent) to every
rendering engine having a copy of every database, in its copy of the
OSM data (*). For especially popular data it could even be included
at planet.openstreetmap.org.
Correct me if I'm wrong, but isn't this already the way mapnik works?
I seem to remember having to download a separate database file while
installing mapnik (**).
(*) Or are you talking about a rendering engine that doesn't have its
own copy of OSM? How does it get the data? I didn't think we were
allowed to have a rendering engine which looks up its data through the
API, so I'm not sure how you'd go about doing that.
