Okay.

What would be your requirements?

I consider the following to be important:

1) Recursive notifications. I.e. one watch for /home/vishesh can notify 
about everything what happens in sub directories of that directory.

2) Reliable notification of file renames. Where is inotify lacking here? 
AFAIR one gets a deletion and a creation notification which are difficult to 
link to one another unless watching the directories it happens in?

Anything else?

Thanks,
