Netfilter based application : any advice ?

["Saber zrelli" <saber_z@fastmail.fm>]

Hi people ,

i'm new in Netfilter community ,
I'm planning to crate a network software robot acting like 'automata'
based on scripts dicting its behaviour .
i explain :

the main program basically filter packets and executes actions like
iptbles does ,  based on rules located in some file.
the difference is that the actions can also be sending specific packet.
the tool should allows for example simulation of tcp/ip connections , ftp
connections and so on.

the implentation will consist on a Netfilter module that will be added to
hook on the network activities.
now the point is :

- Is it possible to send packets with Netfilter or not? ( if not i guess
using libnet will resolve the pb but better to have  
  every thing based on the same infrastructure)

- I would like to have the tool work with wireless protocol , does
Netfilter support non Ethernet proto and 802.11 particulary?


any advices will be really appreciated.
also , any partner for the project is welcome.

Regards.
