Does anyone know how to intercept WRITES and/or TALKS in FreeBSD?  I
am trying to write a Write/Talk interceptor which will allow the user to  
lock out writes from people he/she doesn't want to communicate with.
However....
I am a relative newbie, and I dunno how the Write/Talk setup works.

Any responses - please mail me at murphy@beastie.cs.und.ac.za

Thanx all
