Up to now I have created and uploaded the boundary files manually once a 
month. An "automatic" service for this would be better.
But: Each time I have created these extracts I have found several 
country borders that have been broken. So I repaired them before 
creating the same stuff again and ensured that the boundary extracts 
were uploaded only if the country information was complete.

Regaring Geofabriks dumps: The europe dump does not contain the complete 
spanish border because some parts are in africa and they wanted to have 
continent specific dumps.
Therefore I create my boundary extracts from a planet file, split it 
into 5 areas (america (north & south), africa, europe asia and 
australia-oceania), compile the boundary extracts and merge them 
afterwards.
If you are interested I can send you the steps more in detail (with 
.poly files).
