Multiple apps using same driver.

[Vadim Smirnov]

If two different application operate on different network adapters then yes, they can share single filter driver. Otherwise, no because there is only one copy of the packet in the driver.

So you have two choices, build your filtering engine as a dedicated service process and use from two different applications, or build two different filter drivers, one per application. First approach probably better from the performance point of view.
