Thanks, much appreciated.

To form a lingo maybe we could call this "unprivileged trashing"? Within the 
$HOME directory and maybe even for removable media filesystems without user 
permission support this might be all that is necessary.

If you don't own /foo/bar but have write permission I think the only valid 
trash dir you could create would be /foo/bar/Trash (you're the owner but it's 
world writable, well for those that have access to the parent directory)

I guess never.

As David pointed out in the "trash mechanism" thread when the problem is with 
putting back the file you can drag it to another place.

If the problem is with files still available from the trash after restricting 
permissions one can't guarantee no prior copies exist anyway. You need to 
remember to shred your trash as in real live.

If the problem is that the permission of the directory where /Trash resides is 
restriced the whole subree and trash is shut down too. Though, someone might 
maybe still have fetched a copy before ;-)
