Actually I think Pubsub should be used for discrete modifications (e.g. 
: user modifies some parameters or add a new search engine to her 
browser) and Jingle for large datasets (e.g. : initial sync).

Thinking also that a hash could be included in each sync stanza by the 
server so that clients could determine if they're up-to-date.

Wondering how Google bookmarks sync work. Has someone logged XMPP sync 
traffic on Chrome ? Does it use Jingle ?

Yeah, I agree, it's time you write a XEP for XMPP sync. ;)
