Hello all,

i was investigating the access control model used in tahoe and i was
wondering about that case
consider that alice has folder "image" and she granted access to Bob.


now bob has access to the image folder which means that bob has access to
mypic.jpg, mypic2.jpg,... caps.

after awhile Alice decided to dump Bob away, so as stated in the dirnode
she have to copy (deep-copy) the shared folder to another location for
example "image2".

does deep-copy change the caps of the files mypic.jpg, mypic2.jpg??
if it doesn't so Alice have to remove the image folder to prevent Bob from
accessing these images ??

Best Regards,
Mahmoud Ismail
