Just realized that running on a proxy on each tserver is probably a bad idea.  
It make the user of the thrift API have to handle failure cases (i.e. remote 
proxy I was using failed, now I need to select another).   If you are running a 
local proxy process, there could be failures but I think its much less likely.  
Using a local proxy and letting the Accumulo client code handle remote failures 
seems like a good way to go.
