The question isn't zero-latency. I don't see that being achievable given modern digital technology & laws of physics. Perhaps string theory or some unthought of GUT will get us past relativity but for now...
The question is phase-coherence. There are ways to lock specific processing blocks on the same dsp now, but I think that the newer AD stuff does it at a lower level. I didn't plumb through the entire devkit (which u can download a demo of) but I did read through some of the technotes for the newer Kits & Sharc releases and confirmed some form of support for phase compensation when Red mentioned it to me a while back. I'm sure Frank (and hopefully SC) know a lot more about it than I. I just don't know where the STDM interconnects fit into the overall scheme of things, since u can't just open up Scope.exe in the devkit and see what Creamware sees. I'm sure they can figure it out though...
