I haven’t taken a close look at this yet, but this sounds very very cool! I found it mentioned in Jeffrey Snover’s blog…

PowerShell Access to Windows Mobile Devices

…and then hopped over to the Nivot Ink blog to learn more…

Here’s the feature list from that blog entry…

• Get device information and manipulate and explore the registry with a rich device object returned from Get-WMDevice
• Invoke-Item against remote items to or execute or trigger their associated applications
• Invoke-Item with -Local switch to attempt to execute a remote file in the context of your local desktop (e.g. office docs or images/videos)
• New “Mode” attributes specific to Windows Mobile file attributes: (I)nRom, Rom(M)odule
• File/Folder objects’ attributes can be modified with .Attributes properties just like FileInfos etc.
