What is your platform? I just build a test version of libsprng2 where I enable MPI. It does not seem to affect the use by R --- on an example init I get the same sequence on RNGs with the prior (non-MPI) build and the current one. Good. I'd love to get you that for testing. It's a trivial build in a chroot or directly, and incase you use x86 (rather than x86-64 as I suspect/recall you do) I could send you the lib and -dev packages.
