I'm looking for an equivalent to the SPSiteDataQuery functionality in the Client Object Model (COM).
The CamlQuery can be used with an instance of List to execute SPQuery level of aggregation, but is there an equivalent to site collection level queries for the COM?
Checked the Web object: http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.web_members.aspx and also the Site object http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.site.aspx and don't see anything there. SubwebQuery http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.client.subwebquery.aspx had a promising name, but turns out that it's not what I'm looking for.
Perhaps there's no equivalent functionality in the COM?
Any pointers would be appreciated.
