Is it possible to pull a text file across domains?

Knowing what I do about Flash and sandbox security I am wondering before I attempt to try, whether text data from an outside source can be pulled into for instance jCarousel or jScroller.

I see that jCarousel, "by passing the callback function itemLoadCallback as configuration option, you are able to dynamically create <li> items for the content.<script type=“text/javascript”>
jQuery(document).ready(function() {
jQuery(’#mycarousel’).jcarousel({
itemLoadCallback: itemLoadCallbackFunction
});
});
</script>

And of course I have no intention of pulling in images so jCarousel may not be the best solution.

I was also looking at jscroller2

and jQuery based Newsticker
