Add a shim to the packet capture engine. Before the captured packet gets
set up the stack for traditonal protocol decodes you can check for
conditions like the seq number matches a predefined set and if it does
you can readsomething like the window size and translate that into a
part of a command. If a packet like this is captured it woun't get
flagged by the IDS becasue it never makes it to the IDS analysis phase.
Command response is done by the same shim via packet injection. This
would require some device driver foo. This would not work well if the
IDS supplies its own network card driver.
