BITSY is offered as a complementary technique for WebStorage not as a  
replacement to SQL.

I know how to implement a business application using this technique,  
sorry I don't claim too much familiarity with Web mail.

Each message has a network representation, and a URL to go along. So  
while you are manipulating its attributes, you are essentially  
updating that representation. Of course, you can build a structured  
database (possibly accessed using SQL) to enable the navigation and  
query mechanisms you are interested in. This database can be  
maintained by the proposed interceptors, thus creating a database that  
is only read by applications and updated by the synchronization  
library. All updates to data are seen as network requests as opposed  
to SQL UPDATE statements.
