Gathering Network Statistics

# In PS CTP2v3, .NET access to IP statistics is non-existent. There are no static members 

# for the interface statistics yet, although there are non static members:

[System.Net.NetworkInformation.IcmpV4Statistics].getmembers() | %{$_.name}

[System.Net.NetworkInformation.IPGlobalStatistics].getmembers() | %{$_.name}

# This means network data has to come from WMI or netsh:

$computer = "LocalHost" 

$namespace = "root\CIMV2"
