I'm using the wireless CCK to bridge between the DECA networking and my router. This works well because when you're downloading from the internet, [one my connection is slower] it goes into a buffer as such, and if a packet is missed, then it's requested to be sent again.
This doesn't work with streaming, as there is very little "ask again" time, before it has to be ignored for the streaming to continue.
You can use it to link to your DECA, but it isn't going to help much going the other direction to bridge to your other devices, so the BB DECA and a switch would be better.
In my setup, the DECA cloud (MRV, VOD, TV Aps) is isolated to coax. I have three blu-ray players that we mainly use for streaming netflix/Amazon. One is hardwired from my router. The other two are connected via wirless n bridges, and seem to perform OK, even streaming high def stuff, but Netflix will usually start in SD until it builds a bit of a buffer then switch over to HD.
I guess one of the main reasons i went this route, is because I already had the bridges, and didn't really want to split the coax to add another DECA at each reciver to bridge the blue rays
