Hi list,

I wonder if someone has already tried the following.
It could be useful to trigger some action whenever
a subtree is modified.
This would require to attach a hook to the subtree,
which can be done using a property drawer.
The real problem is how to (efficiently) track
the fact that some subtree has been modified?
Maybe by keeping an md5 sum and checking
if it has changed when writing the file.
Any other idea?

Thanks for your inputs,

-- 
Fabrice
