Hello
1. I can see from the architecture.rst that if there are fewer servers than expected, tahoe loops, but I've got 12  (>10) storage servers and default setup. Can I confirm it picks 10 of 12 randomly?

2. What is the current status of the sync and mirror commands? I can't see them in the cli but I can in the history of the project. 

We want to run a grid for clients. Many of our clients are satisfied for us to run their storage client for them (though some will not), which means they largely will connect to it over https. I've looked at the docs and i need clarity on these:

3. Once shares are written to the grid, exactly what command is run to tabulate the overall space used by a specific account?

4. How do I list all of the accounts in the grid?

5. With our test setup, I create a resource, and share it by sending the URL to my friend. But what is the most efficient way to unshare it?

6. If clients run their own private storage clients, how can they share files in it to friends given they are in normal consumer adsl situations with router firewalls denying access?

7. Is it possible to white label the tahoe storage client web interface? I guess by building our own and using restful websvcs internally? 

Thanks ever so much.
