+Share picture.
+
+I take a picture in a family party and I want to share it with my
+family. I can simply send an e-mail to all my family contacts. Or I can
+share with them by using their prefered method, and make it easier to
+search the picture by submitter, tag, etc. And I want to allow them to
+comment, etc. Damn! E-mail allows all of that, and has allowed for many
+years.
+
+OK. Subscriptions and channels are good features (mailing lists solve
+that as well).
+
+Where is it stored? Locally, on every subscriptors computer? Do
+store-and-forward just like MTAs do? What does the network look like? Is
+anybody going to keep their computers on, and share the load? What are
+the guarantees? Use supernodes? Use tor or tor-like onion routing? Or
+simply end-to-end encryption?
