[tahoe-dev] Tahoe Access Control

[Brandon Meskimen]

Peter,
         Thanks for the example. Is it possible to change the file so
instead of ReadWrite access you change it to Read only? If i wanted to
prevent someone from accessing that file could i just delete the link? The
tree graph design is very good by the way.

Regards
Brandon
