Yes, certainly. CloudMade does that, or at least used to do it.

We generally say that if the layers are transferred to the client 
separately then yes; if OSM is merged with other data then no, but this 
is just an interpretation used by many in the project and not a legal

Anything derived from CC-BY-SA data must always be CC-BY-SA too.

If you publish something under CC-BY-SA you can never exclude commercial 
use. You can, however, exclude commercial use of your infrastructure. 
This means that you could say "only noncommercial users may download 
from my web server", but if someone else then noncommercially sets up a 
mirror that can also be used by commercial users, you cannot prohibit that.

If OSM data is instrumental in the point being created then it is 
certainly a derived work. (It isn't a derived work until step 3.3 
because OSM data only comes into play in 3.4.)
