Mikey Bronowski gives us a glimpse at the power of MSX/TSX:
The MSX (master server) can be used to define SQL Agent jobs that then will be pushed over to one or more TSX (target servers). It is possible to see the server is either MSX or TSX when looking at SQL Agent in SQL Server Management Studio Object Explorer. The master server can be identified by (MSX) next to the SQL Server Agent. It will also have two subfolders under the Job folder: Local Jobs (for regular jobs) and Multi-Server Jobs.
This is something woefully few database administrators take advantage of. As the number of servers you have to mange increases, ensuring consistency in SQL Agent jobs becomes more and more difficult. MSX/TSX admittedly has some rough edges, but the tool does a lot.
