NAC solutions?

["Gibbs, Jason" <Jason.Gibbs () paradigmhealth com>]

Hey all, I was wondering if anyone has delved into the NAC realm. I have seen demos of various NAC products from 
Mirage, Insightx, ForeScout. Etc. and they seem great for internal protection if they indeed work as good as they say 
I am looking for an out of band clientless solution. We already have Cisco 802.1x capable devices. 
So basically has anyone implemented a NAC solution or are you in the planning phase for a NAC solution. Endpoint 
security is my main concern for our 2008 budget.
TIA,

Jason
