Idea related to UNIX directories

[Steffen Mazanek]

Hello,

at first I have to say, that I am new to this
mailing list and if my proposal is absurde please
don't plonk me :-) I am no kernel freak and so
I can not implement the following idea.

I think it would be quit useful to allow some 
code to be related to e.g. the i-nodes of directories.
Consider therefore an example. At first, all
directories have a default assignment to save
memory. This default assignment may realize
permission related stuff. Now some privileged users
have the permission to add their own code, which
must implement an interface and some standard 
functions and in addition they are able to trigger
some events, e.g. write something to a log-file
whenever a user enters the directory or start 
an application.

What do you think about this idea? Is it feasible
at all?

Best regards,
Steffen Mazanek
