Not only that, but clients and the server have to be updated  
synchronously. While this might be easy for webmail clients, it's an  
impossible tasks if users are using desktop clients to manage their  
sieve scripts.

Maybe this only a theoretical problem. Is there any desktop client out  
there that *generates* Sieve scripts, i.e. not simply download and  
upload complete scripts like KMail?
