No. Distribution of the shapefiles is up to you. However, **if** you 
distribute the shapefiles, you have to do so according to the CC-by-sa 
license.

If you are distributing the data to your clients, then the answer is "yes".

... yes ...

No. The CC-by-sa license tells you *how* you must redistribute things, **if** 
you choose to redistribute them.

You are not required to forcefully redistribute stuff.


The details about how the upcoming ODbL license will stand up against these 
use case are still not clear. Expect the same general stuff: you should not 
be forcefully made to publish anything, but if you use data from a 
ODbL-covered DB, you have to allow access to the derivative DB.
