BTW, this diagram (and the similar diagram on the allmydata.org home page)
shows the web gateway as only having an HTTP(S) server on the client side.
Maybe I'm being pedantic, but it really has separate HTTP(S), SFTP and FTP
servers, when they are each enabled. (SFTP and FTP have nothing to do with
each other.)
