Bringing IT back Home?

Recently, with the changing economic conditions outsourcing and offshoring are once again taking center stage. I would like to hear from anyone who has either brought previously outsourced IT functions back in-house, or is in the process bringing the outsourced IT functions back in-house or is in the analysis phase ? considering bringing the outsourced IT functions back in-house (complete or partial insourcing).

I am trying to assess the challenges of outsourcing reversal (backsourcing) as this movement seems to be picking up steam based on the number of outsourcing failures.

Please let me have your thoughts.
