Actually, there's a rather notable problem with that code. It's leaning on the old XPath style CSS selection. That works fine in jQuery 1.2.x, but was deprecated, and this code won't function with jQuery 1.3, which was released in January.
http://docs.jquery.com/Release:jQuery_1.3 - first bullet under the Changes section says "The '@' in [@attr] has been removed. Deprecated since 1.2 this old syntax no longer works. Simply remove the @ to upgrade."
So really, it's one quick and easy change. Just drop the @ and you're set.
Of course, it's dependent on the person's page to execute JavaScript, but even with the popularity of things like the NoScript plugin for Firefox, I imagine it'd be fine for most people. :)
