+1 the scripts would be quite simple :
On user 1 :

PHP Code:

<?php
xcache_set("mona_test150112", 'This data was set by user 1', 120);
print('mona_test15112 was set by user 1 for 120 seconds');
?>

On user 2

PHP Code:

<?php
if (xcache_isset("mona_test150112"))
{
    print xcache_get("mona_test150112");
}
else
{
   print ('mona_test150112 is not set.');
}
?>

I haven't tested them as I don't have xcache yet
