OK.  Perhaps I should have asked *when* you prefer RJS.

Hmm.  Why the visual effect here, rather than in the completion handler

rather than simply handing a JSON packet to the client.

I'll think about this further, though.

Which I don't like to do.  Thanks for confirming that this is actually 
the case.
