Indeed, on multiuser systems, it would be prudent to have database names 
prefixed with user IDs, e.g. "user1/photos" and "user2/photos". This could 
end up being quite common if, e.g., blogging software starts using these 
databases and many users on a host all install the same blogging software.

Well, part of the problem is that we want databases to be accessible 
regardless of path. For example:


...should all be able to access the "user profile" database, regardless 
of which one created it.

It's not entire clear to me how to resolve the issue.
