PowerShell, JSON, oData and CRM 2011 (or SharePoint 2010)

I am working on how to consume data from/to SharePoint 2010 and from/to CRM 2011. I decided to try and see if I can get the data to display in PowerShell, figuring if I can get it there, I should be able to get it anywhere?  Here is the code to loop through all the Contacts in a CRM 2011 deployment.

Took me a while to figure this out. Should work with any oData source?

$url="http://your.crm.server/Instance/XRMServices/2011/OrganizationData.svc/ContactSet"
$assembly = [Reflection.Assembly]::LoadWithPartialName("System.Web.Extensions")
while ($url){
	$webclient = new-object System.Net.WebClient
	$webclient.UseDefaultCredentials = $true
	$webclient.Headers.Add("Accept", "application/json")
	$webclient.Headers.Add("Content-Type", "application/json; charset=utf-8");
	$dataString=$webclient.DownloadString($url)
	$json=new-object System.Web.Script.Serialization.JavaScriptSerializer
	$data=$json.DeserializeObject($dataString)
	foreach ($result in $data.d.results){
		write-host "$($result.FullName) , $($result.EMailAddress1)"
	}
	Write-Host "Press any key to continue ..."
	$x = $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
	if ($data.d.__next){
		$url=$data.d.__next.ToString()
	}
	else {
		$url=$null
	}
}

To loop through the items of a SharePoint 2010 list, you would change $url to:

$url=”http://sharepoint2010.server.com/_vti_bin/listdata.svc/Announcements”

Not sure if this would be valuable to anyone, but here it is!
