I think the reason this hasn't been done is that inotify_add_watch()es
are non-recursive:  you'd need a watch over every directory, and you'd 
need a crawling step (churn, churn) to enumerate the directories to
add watches for.

Beagle (which only indexes home directories, by default) uses an 
algorithm for placing watches as it crawls, such that by the end 
of the crawl you can guarantee not to have a lost a race on new 
directories being created while the crawl was happening:
