None of the USB nor firewire standards provide for positive retention.  eSATA does sort of in some variants but the connectors for USB are especially delicate and easy to break off and destroy.  There's the size of the Cat5/5e/6 cable to be considered too.

If you look at the Raspberry Pi though, it takes a substantial piece of real estate
though. Not everything needs to be industrial strength connectors as witnessed
by USB and HDMI -- if they fail I'm just as unhappy as if ethernet fails. Surely we
want keep shrinking these cute little purpose built controller-like things and not
*have* to rely on wireless as the only other space-saving means?
