Unfortunate to hear that.  It was brief and to the point.  If a 6500 NAT 
knowledgeable person would have been hired, they would have steered 
clear of it.  Design around it.

What do RFPs have to do with it?  RFPs are typically SUPER counter 
productive and would have been 100% useless to the OP's issue.

If by "we" you mean the trading industry, yes you have some serious 
talent pools there.  I've done my fair business in the trading business 
and there are some top notch talent in that industry.

True.  I've been there.  But I know as well as you do there is a lot of 
money running across these networks.  IMO the talent and knowledge is 
there, you just have to find it.  Whether it's a referral or searching, 
that diligence is up to the purchaser/owner of the equipment.

That's exactly my point.  I explicitly stay far away from NAT on the 
6500s.  Just because a feature is there at your disposal doesn't mean 
you should use it.

They have a good handle on it.  But, some don't.  And, a lot of people 
don't have experience in the trading vertical.  So, how can you assume 
they understand their business and what their needs are?
