Your Missing Manual article about MySQL Federated Tables is great. To me, although a very important part is missing. It's the part concerning executing remote commands using federated tables and views. In your article you write:
"The full implementation of the framework requires some more components to allow different users to execute remote commands concurrently, and some additions to allow the execution of arbitrary commands, but I won't burden you now with such details. I plan to describe the full framework in a separate article."
Has this article been written in the meantime? If not, could you be so kind to put me into the right direction concerning the missing parts for this sollution?
