Including posts/records from other multisite

Hi all,

Is it possible to include, for example “latest news”, from website nr1 in to the theme on website nr2. Currently i just call it out on website nr1 with:

function get_latest_posts_news($amount, $start) {
   rewind_posts();

   $last =  $start + $amount;
   $lastposts = get_posts("numberposts=$last&order=DESC&orderby=date&category=3");
   $i = 1;

but ofcourse category3 isnt the same on website nr2, is it possible to do this? ifso, how?!

Thanks!
