Hi Paul,

Sorry for the delayed answer :(

Yes, it will be really useful, thanks.

I will try to do both wrapper (PCI, platform), but I do not know how much
time does it takes because I am really busy at the moment

You know the hardware better than me, so: have you other suggestion
to point me on the right way?

Thank you :)
