Capturing instant messages

[Ed Leafe]

	I've been approached by a local business that has been advised that  
they need to start capturing and archiving their instant messaging in  
order to comply with Sarbanes-Oxley. The company is largely PC, but  
has a significant number of Macs running OS X, too.

	Googling around quickly turns up IM Grabber for the PC, which would  
seem to be just what they need. But there is no equivalent to be  
found for OS X. So if anyone knows of any such product, please let me  
know and there will be no need for the rest of this post.

	But assuming that there is no such product, would it be possible to  
create something in Python, using the socket or a similar module?  
They have a number of servers that provide NAT for each group of  
machines; I was thinking that something on those servers could  
capture all traffic on port 5190 and write it to disk. Is this  
reasonable, or am I being too simplistic in my approach?
