Andrew, please have a look at this when you get some.
This re-implements some of the coprocessor logic.
I think with Scott's latest patch it is possible to do this wit pure coprocessor that make use of the processRow helper method on HRegion.
(I.e. no need to maintain separate RowProcessor implementation for each type of operation at each regionserver, but instead just use coprocessor endpoints).
