[IronPython] Embedding Powershell and Write-Host

[Curt Hagenlocher]

Looking at the definitions of the C# classes in that blog entry and given
that you're hosting PowerShell inside of IronPython, I see no reason why you
wouldn't be able to implement the derived types in Python itself.  But the
link seems to do a pretty good job of giving minimal implementations for
both classes.
