Thanks, that's quite cool.

Do you know if there is anyway to automate the logon? My application needs to create a report, Zip it up and upload it to SharePoint automaticaly. Application user is not the SharePoint user so I need to embed the logon/upload/logoff into my app, do you think that is possible?
