Monad is definitely a hot topic to watch in the future. I've just discovered that Jeffrey Snovers two webcasts about Monad are available for on-demand viewing. If you want to find out more about the future of command line scripting, these are a good place to start.

TechNet Webcast: Next Generation Command Line Scripting using Monad (Part 1 of 2)
Presenters: Jeffrey Snover, Architect, and Jim Truher, Program Manager

What is the next generation Microsoft command-line shell automation and scripting technology (codenamed "Monad") and how does it fit into the realm of tools and languages? To find out, join us in this webcast, one of the top rated sessions from Tech·Ed 2005 in Orlando, Florida (MGT320), as we highlight how the architecture of the shell supports consistent, production-oriented commands. Learn about the power to navigate and manipulate multiple data stores, and see how the powerful command-line shell uses objects to simplify scripting.

TechNet Webcast: Next Generation Command Line Scripting using Monad (Part 2 of 2)
Presenters: Jeffrey Snover, Architect, and Jim Truher, Program Manager

Join us as we drill down into more details of the functionality of the next generation Microsoft command-line shell automation and scripting technology, codenamed "Monad". First we conclude the scripting examples from the first session, then move on to advanced scripting constructs. We look at writing secure scripts, using script blocks for maximal power and flexibility, leveraging the shell's dedicated streams for RESULTS, ERRORS, VERBOSE, DEBUG, and PROGRESS, and dealing with errors, exceptions, debugging and tracing.
