Cross Site List Access

Hi,

Within the many excellent examples you have provided, lists seem to be accessed using the following general approach:

## Get the tasks list

#set( $tasksList = $web.lists.get_item("Tasks") )

which, in this example, requires that the 'Tasks' list exists within the current site.

I would like to use the DataZoom webpart in Site A and to access a list within Site B, but am unable to figure out whether 

this is possible, and if so, the format for the script I should be using. Any help would be gratefully appreciated.

Thanks, Robin.
