Recommendations for a Passive Web Content Monitoring solution?

["Nick Jacobsen" <nick () ethicsdesign com>]

Not sure that this is an exactly suitable topic, but anything seems to go,
so...

I am trying to find an open source (read free) PASSIVE web content
monitoring solution.  We are looking for something that can be put on a
network, and using promiscuous mode, capture and analyze web traffic, etc...
We would obviously place this in such a way that all network traffic would
pass by it.  Any suggestions would be welcome, though again, I am looking
for something specifically designed to do this, as I know I could modify
existing tools myself...
