Feature Request: getJSON

Feature Request: getJSON

My applications all use a caching service and the random callback
function name generated by the getJSON call breaks it. I would like
to be able to pass in a static callback name on the getJSON call so
that I can cache the results of those feeds. I understand there are
risks involved with this approach but for people who cache their feeds
the current implementation just doesn't work.
For now I've had to build my own JSONP method that does this but it
would be nice to tell clients they can use the jQuery method as most
of them already use the library.
Thanks!
Jim
