Any sniffer would pick them up.  In fact, I'd
recommend using Ethereal, and after an extended
capture, simply click on any one of the packets
included in the IM session communication and use the
stream reassembly functionality...boom, you've got the
whole conversation.

Now my question, is how secure are normal "ims" on
AIM. How difficult =
would it be to listen to anothers msgs and if at
all possible, how could =
this be fixed.=20

       "msgsnarf  records  selected messages from
AOL Instant Mes-
       senger, ICQ 2000, IRC, MSN Messenger, or 
Yahoo  Messenger
       chat sessions." (msgsnarf(8) manpage)

AFAIK, none of the above protocols are usually
encrypted. dsniff

(http://www.monkey.org/~dugsong/dsniff/dsniff-2.3.tar.gz)
can pick them up.
