Quake problem?

[mj () SMACKDADDY NET (mj () SMACKDADDY NET)]

I apoligize in advance if this seems unimportant or if anything resembling
this was ever posted in the past.  I looked through the archive and came
across nothing.

In playing with a friend of mine's code (dcd3 by Volatile) and combing
through the bugtraq archives...i came across something that i found
interesting.  In May of this year, Ambrose Feinstein said...
"actually, using the attack on yourself for the same set of servers would
work too; if a netquake server gets a connection from an ip already
connected, even on a different port, it drops both."
Assuming this is correct, what stops anyone running a variation of unix to
send a spoofed packet to the quake server of anyone they dont like and
having the quake server drop both connections?
This would cause that person pinging 300+ and getting wooped by the person
from the edu pinging 130 to have full control over whether the person
could play or not.  Just a thought....Lemme know if anyone can produce
this with some success.
