Does anyone know if it is possible to develop something to get a list of pages that have not been transfered with Courier?  I know that this does not exist natively, so I am looking for a way to develop something new or a workaround.

My ultimate goal is to create a summary dashboard to display all pages on our staging server that have not been transfered to our production server. 

I need to display:

• pages that are new on staging and don't yet exists on production
• pages that have been updated on staging and havent been pushed to production (basically comparing modified dates)

We are using umbraco 4.0.3 with courier 1.1.1

Thanks!
