Woop Woop! Danger Will Robinson.

There are some inherently problematic issues with a send the packet
with the alert output approach.

First is the lack of anonymization and potential disclosure issues
sensitive sites will have with this.  Don't expect much participation
from sites that process sensitive info.

Second is the traffic load.  I hope you have the mother of all internet2
links to be able to handle the traffic load a few hosts doing wide scans
that triggers a lot of alerts create.

Third is the DOS potential.  You will be creating an interesting traffic
mirror.  A clever attacker may figure out how to trigger off alerts
not only on inbound packets, but the outbound packet may trigger as
well if not compensated for. Uh-Oh... :-)

Care is advised,

P.s. Why do you need a snort plugin for this? The snort unified output 
system seems like it does everything you need including providing binary
packets with alerts.  You more likely need a barnyard plug-in and a
cron job, imho.

       0 = 1 , for large values of zero and small values of one.
