I found an article by Tamara Davis and Charley Lineweaver called
"Superluminal Recession Velocities"
http://astro-ph/0011070
the date shown is Jan 2001, though the number suggests late 2000.
It is 4 pages so easy to download and it is specifically on that topic-----Lineweaver's longer 2003 general survey is actually better as a source of information but not as focused on that particular topic.
Basically it is just the difference between the highly local "special relativity" (where there is that speed limit) and GR (where there isnt) and there is no inconsistency-----SR only applies in a local coordinate patch and forbids one thing PASSING BY another at any speed over c. They explain this adequately in the first paragraph entitled "Two Kinds of Velocity"
