I probably think so. I will check it out anyway.

I'am pretty sure about that, they have couple of people working on that bridge 
to keep it going, they do sublicense it as OEM products, which fairly 
diminishes the aspect of dumping it.

But there could be changes in the ASIC and or firmware as the firmware at 
present is not great to talk about. 

Potential problems could occur when there is a lot of change in the firmware. 
Even the timings could change etc...
