Mar 11, 2014 at 21:23 comment added user27578 @BMS, that Wikipedia article is incorrect. If you computed the separation velocity of objects moving with the Hubble flow as comoving distance over cosmological time, you would get zero. That's the whole point of comoving coordinates. FTL recession velocity is what you compute if you take proper distance over cosmological time.
