If you're reasonably comfortable with sockets programming then what you
describe can be done using a divert socket and the ipfw firewall (with no
need for a kernel extension).
Read 'man divert' and 'man ipfw' for more information.
As an added bonus you should be able to put much of the packet selection
logic into an ipfw rule and only receive packets that your application is
likely to find interesting.
