Fast ping function for Powershell
Does anybody have a fast function for pinging a list of machines using Powershell? I know I can use Test-Connection: Test-Connection -Count 1 -ComputerName (gc .\comps.txt) -ea silentlycontinue but this seems painfully slow (I'm assuming because it uses Win32_PingStatus).

Would you recommend Iron Ruby, Iron Python, or PowerShell for making a C# application a script host?
After some quick tinkering, right now I'm leaning towards powershell for two main reasons (note these a purely my opinions and if they are wrong, I'd love to know!!!): 1) It's simple to create a runspace with classes in your application, and therefor easy to make your application scriptable. 2) I've heard some rumors that IronRuby and...
