It is the scatter/gathering of data that is killing. I need to have one
and only one transfer on the PCIe line for each period to be efficient,
preferably in the 10 - 20KB range or more.  The jack model of one
channel, one buffer does not fit very well here.

Potentially It should also be possible to stream from harddisk via DMA
directly to the device without bothering the CPU at all. That OIOH hand
would work for prerecorded material with say ardour, since you can look
ahead as many bytes as you like. 

Doing live performances requres another approach though. 

Do you believe it would be very difficult to implement? I do
unfortunately not have the required knowledege of jackd internals to
judge wether or not.
