PubShare: Crowdsourcing Permissions for Group Communications
People need to share to get their work done, but today's
environment makes that hard for both the people doing the work and
those administering the systems they use. Because people can't easily
delegate subsets of their permissions, administrators become
overloaded with work, which leads to long wait times. Long wait times
encourage people to work around the system, making things both harder
to use and less secure. We can do better, as illustrated by PubShare,
a tool developed by Marc Stiegler for managing group communications.
At its heart, PubShare is a publication/subscription service that
conforms to the Amazon Simple Notification Service interfaces, except
for the access control parts. Normally, an
individual is either a publisher or a subscriber of a topic. However,
when a group of people are both publishers and subscribers, the topic
behaves more like a wiki. The unique feature of PubShare is the way permissions are managed and
responsibiltiy assigned, which are best explained in
a five minute video.
PubShare is based on the prinicples of
Rich Sharing. More detail is available from the
You'll notice that PubShare never interrupts you with annoying
security dialog boxes. That's because supporting Rich Sharing makes
it possible to build user interfaces that have
no clicks for security.

PubShare is experimental software that is not supported by the
Hewlett-Packard Company. It may stop working or lose your event
history at any time. While all communication is over HTTPS, the data
you post is not protected by encryption or other means, so you should
treat such data as public. Use your PubSub Feedback Topic to send
comments and to ask questions, or send your comments and questions to
