Question

Is it possible for me to supply a client with a snippet of HTML which contains a reference to a javascript file that I host? They want to paste this HTML into their CMS, so that when their page loads, it’ll load our content.

I was under the impression that there was cross domain security preventing this from being possible.

What if, instead of linking to the JavaScript, I gave them the snippet of HTML with the JavaScript already included

so instead of

<div>
    <!-- link to js -->
</div>

I gave them

<div>
    $.get(/*url to my content*/);
</div>

Would that work?

You could use JSONP to simulate cross domain AJAX calls (works only with GET requests as internally it uses a script tag):

$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?",
    function(data) {
        $.each(data.items, function(i,item) {
            $("<img/>").attr("src", item.media.m).appendTo("#images");
            if ( i == 3 ) return false;
        });
    }
);
