TODO

TODO's:
--------------

 1. Buffer moves to bytes instead of packets. We use 2 buffers of equal size: the first contains
    the data, the second maps the received/unreceived data: 1 for data present, 0 for data not
    present. [DONE]
 2. Header optimization (e.g.: codec down to 1 bit) 
 3. http://msdn.microsoft.com/en-us/library/aa365924.aspx to find the source IP address to
    set in the packets	[DONE: net_get_local_ip() in net.c/h]
 4. read from stdin and write to stdout
 5. channel management (t1 for control, t2-tn for data connection)
 6. code cleanup
 8. UI
 9. API
 10. find live hosts to spoof
 11. support for xp sp2
 12. dll injectiom
 13. Fix a bug: when spoofed source ip == ip of master and there's no bind inbetweet (e.g. as we did it for testing)
     the master will quit the connection for some reason. This is no real big problem as a scenario without DNS server 
     inbetween is unlikely, but better be solved anyway...

99. grep for TODO in all the source files and do the todo!

 1. Add CNAME support (?)
 2. Investigate DNS Extensions for Data Transport (http://www.ietf.org/rfc/rfc2671.txt)
 3. Add support for multiple TXT entries in one response (up to 1k per packet)
 4. Response to spoofed requests must contain an IP, in order to avoid IPS signatures based
    on NXDOMAIN. Note: the responses to spoofed requests should trigger lots of PORT UNREACHABLE.
    However, we can use 135 as a source port. Or just rely on the fact that windows firewalls will
    simply drop the unsolicited packets :)
