Part 1
Holly Mistlebauer Open discussion of desktop firewalls by participants.

Break [free food! :-) ]

Part 2
Chris Danis Linux-based network firewalls.
Bill Klinko Linux box firewalls and Windows server firewalls.

I couldn't find anyone to cover desktop firewalls, so I am going to follow Oliver's recommendation and lead a discussion among attendees.

Currently:
Chris Danis Linux-based network firewalls.
Bill Klinko Windows server firewalls (we had a problem with the ILLiad server that I find interesting) plus Linux box firewalls (which is not the same as what Chris is talking about.)

Missing: Desktop presenter(s).
