Ray, to avoid duplicate effort, I'm working on implementing "stored 
scripts" for Infinispan based on ScriptEngine.
Scripts would be stored (compiled if possible) in a dedicated replicated 
cache. The scripts can then be referred to by name in dist-exec and 
map-reduce invocations. It will then be possible to invoke these scripts 
both locally and remotely (over HotRod and REST).
