Provide list data to business data columns in a different site

Hi All

I'm looking to find a way to share list data across sites, so that the data is available in lookup columns. The current lookup column type only allows lookup from lists in the same site - could the BDC be used to access data in lists in other sites via the Sharepoint web services? then I can make use of the new Business Data column to achieve this. Has anyone done this and could post a copy of the application deifnition they used?

cheers
