It might be interesting to modify the protocol (and the backend at the 
point of projection to the front end) so that a user defined formating 
function could be applied and either accepted or rejected by the front 
end. Perhaps one flavor of XML output is a start, but I could imagine 
wanting a custom or even different "standard" output format.
