I had been hinting recently about some news coming from an established PowerShell vendor: /n software has just announced version 2 of their NetCmdlets HERE. It is currently available as a beta release.
Some of the improvements are noted on the page. Not currently mentioned on the page is that some of the cmdlets now support scriptblocks for values passed to parameters (I don't know which do and which don't).
Now, they've bundled their PowerShell remoting solution into one package.
I'll be blogging more about NetCmdlets soon. I plan on doing a session on them for my virtual PowerShell user group, and also for the UK PowerShell user group soon.
