Is it enough like crossdev enough to share code, with perhaps a bit of 
abstraction? Maintaining the same thing twice is rarely a good idea...

Seems like people already committing cluster stuff to the sci overlay 
could help; maybe they'll port packages, fix bugs, etc. With a new 
overlay, we'd have to start from scratch, and I don't really see the 
point.
