Topic: RayDat with Protools 9 and Mackie D8B (Mac Pro)

Hi
I'm considering getting a RayDat card for my mac pro, so I can track through my Mackie D8B using Protools 9. The D8B has 3 a-dat cards and I'll also want to use it as a HUI via the midi in/out.
Can anyone tell me if this will work or not and if there are any known issues with such a set up. I must admit to my ignorance over clocking issues. Will there be any problems with this?
Any ideas will be greatly appreciated.

Regards

John
