To be honest, I don't frequently have occasion to wander over to R-devel and most of what goes on over there is over my level of easy-readability but I'd feel pretty confident that anything involving interface to another program on a socket or lower level is squarely their territory while file-reading and up is R-help, based on what I've seen. The moderators may wish to correct me. 

I'm happy to spitball ideas privately and you have my email, but I'm not qualified to make specific feasibility assessments on the record so I'll have to punt if you want official answers.
