I couldn’t find any other way, so I really need a filter driver. I wait a news from you.
* Did you find the issue in Xen?
* Do you have plan to solve it?
* Do you have any implementation of WinPKFilter with WFP Callout Drivers? I think it would be more simpler and less bug such as this sample:

* Do you have a tool to removed the need of Microsoft signing for Windows 2008 64 bit drivers ?
