Many thanks! But is not exactly what I want. It's not portalbe, and pure Perl:

"PerlFS is a combination of a Linux kernel module and some Perl scripts which allow to write filesystems in Perl. It currently works with Linux kernel 2.2 or 2.4..."

But I will take a look, maybe to integrate my module to the system or make a XS for it, since for now it has access only from Perl programs.

I was thinking that I can make an extension of this module to make some IPC, for shared memory for any OS!
