You could write a %dopar% backend for the foreach package, which would 
allow any code using foreach (or plyr which uses foreach) to parallelize 
using your code.

On a related note, it might be nice to add Bioconductor-compatible 
versions of foreach and the plyr functions to BiocParallel if they're 
not already compatible.
