It is an interesting thought to provide an service in which authorized 
users can provide jar(s) containing Accumulo iterators to be dynamically 
loaded and available on request. Could have a lot of merit coupled 

Regardless, I like the general idea of a classloader outside of the 
cluster's local filesystem. That does open the door to a lot more 
difficult problems as John alluded.

I do believe it's worth noting that security is only one application of 
cell-level visibility. Using visibilities/authorizations as a filtering 
mechanism for application logic is an intriguing subject.
