Well that's ok right? The fd is created alreay, changing file/dir
persmissions does not change
a thing.

You mean the translation from exec to app id, like here:

http://lists.freedesktop.org/archives/xdg/2011-May/011928.html

You get the pid, and thus the execname, and not the app id like
org.freedesktop.LibreOffice.writer I guess LibreOffice is using.
Knowing the app id maked it easier to get the icon etc.

Yes I agree. Thats now exacly what I've created. The construction is
independend from the desktop,
you can use it also when logging in from the text login, and does
provide the same services to anyone/anything, access to local
hardware, network services like SMB shares and internet services like
Google Docs and Amazon S3.

So the apps/desktop does not have to offer that, the construction
provides that. But then it has to be used by more users than me.

I agree totally. But you have to offer a "safe remove" command.
What do you do for SUSE? direct io?
