> I wanted to ask whether there'd be any support for adding JSONP[1] to the json results format. This would probably also involve the Protocol doc. It would allow easier use of sparql from within browsers. I'm not sure how prevalent support currently is, but I believe both ARC and Joseki currently implement JSONP.

I'm not an expert in this, but as I understand it, JSONP will be
obsolete when CORS is adopted by enough browsers.  I guess I lean toward
including it, but with some words about the security problems is raises
and its expected obsolescence.  As I understand it, the big problem with
JSONP is that you go from merely trusting that the endpoint is giving
you the data you want, to trusting it completely (within the sandbox of
the app itself).   Since there are lots of apps that don't really care
if they are subverted, and the alternatives are difficult or not yet
available, JSONP is quite useful.
