Sorry about the very slow reply, Sam.
That's a good point. The use of the closure could result in memory leaks
depending on what the rest of the code does. They should be fixable -
closures in and of themselves don't cause leaks, but they can result in
circular references to DOM objects in IE. It would be good to test this and
make sure it doesn't cause a leak.

Yes, closures are standard JavaScript and work in every version of
JavaScript since 1.1 or 1.2, I forget which.

Then you'll get an error when it tries to call the closure function with the
jQuery argument. Of course, the same thing would occur if you coded a plugin
the traditional way:
jQuery.fn.foobar = function() {};
