Multiple Cores

Multi-core based machines are now a major factor pushing forward the viability of natively run DAW's such as Reaper and many others.

There was a fairly extensive thread in the Steinberg Nuendo forum which outlined some issues with Steiny DAW's properly managing multiple cores. The problem was somewhat masked with four cores but seemed to be highlighted with the introduction of Dual - Quads. The problem was most noticable when latencies dipped at and below 64 samples. For some reason the single Quads outperformed the Dual Quads - Steiny later came out and admitted that there were issues with the way their managed multiple cores.

So many of the major DAW's have come out stating that they are multi-core ready but this technology is all so new I am wondering if the issues are only Steinbergs. When you couple the 'newness' of the technology with the fact that the two majors (Intel and AMD) have different CPU architectures I wonder if it is possible to make a blanket statement that your DAW (any DAW) is multi-core ready.

From a programming standpoint, is it a fairly simple task to make a DAW like Reaper multi-core ready?

Can DAW companies truthfully make blanket statements like Multi Core ready ?

Are there different considerations in programming for managing multi cores with AMD VS Intel chips?

Is there any forseeable issues in moving from 8 cores to lets say 16 cores ?
