Time Tracking with TFS - instant time sheet!

I found this utility on CodePlex and it works very well for me: updating the "number of hours worked" on a pre-selected Work Item in TFS from the System Tray. Then I can get a time sheet or billable hours summary from SQL Server Reporting Services easily.

And for those of you moving data between Team Foundation Servers, you know the effort of dealing with all that XML. But then I found the Work Item Object Mapper on CodePlex. I haven't used it in anger yet, so I'd like to hear from you if you've used it, especially with local language Process Templates...
