This sounds like something we want to support.   We were discussing
today under what circumstances files and media libraries could
usefully be put into the datastore; and how to support explicit
sharing of 'published' materials in a way that can be programmatically
loaded into the current working environment
for other activities.

Then perhaps there's a need for world-readable space that each
activity can control.  Any activity that has network privileges can
access these kinds of readable spaces on other machines; it should be
able to access such spaces on its own machine as well.
