Do you have a link for some info about this?  Google isn't bringing up much.

There are two basic approaches for doing this: 'old school' and 'new school'.  
For the old school method, you need a console that provides the ability to 
remotely control and monitor the fader on/offs by means of GPIO (most 
consoles aimed at the broadcast market offer this, but many intended for 
recording or other non-broadcast use do not).  Then it's just a matter of 
wiring those GPIO lines to a Rivendell system.  This approach has the 
advantage of flexibility: it really doesn't matter what type of console is 
being used so long as the requisite GPIO remote functionality is present.  
The downside is cost and complexity: you need GPIO hardware for the Rivendell 
system, plus all the physical wiring to interconnect the two.

The new school approach is to make the whole thing virtual; instead of a slew 
of physical interfaces and wiring, the remote functionality is accomplished 
by means of data messages sent through the TCP/IP network (or possibly USB, 
though I am aware of no broadcast products at present that work that way). 
This can dramatically reduce complexity and cost, but it means that Rivendell 
must understand the control protocol used by the console in question.

At present, there are three console 'families' that Rivendell knows how to 
interface directly with in this manner.  They are (in alphabetical order):
