If I understand it full duplex does not double the download speed.
But rather upload can progress at the same time as download.  This
can be useful for a file-server where my reads do not conflict with
your writes (on the network wire).

For download the ACK packets can flow without interrupting the
up/download. Thus it can be possible to approach the theoretical 
bit rate in any one direction.

Am I confused?
