I cannot speak for USB with N wifi but do run an ath9k PCI card as a Hostap server with N speeds, although not 5 GHz. It runs fine as WPA2 CCMP. It is getting more features as it matures.(I have run this setup for 2 years now)
I also have an Intel 4965AGN mini PCI card in a netbook that only works to 150 Mbps(be careful of this some cards only do 150 not 300), it has worked well on 5 GHz at Google cannot remember the exact speed, sorry.
On a Ralink RT2860 I have seen 90 Mbps iperf through concrete to the ath9k 2.4 GHz Access Point I mentioned above on Ralinks own proprietary drivers. Last time I tried with the rt2x00 or Testing drivers I had issues.
A good starting point might be :

Subject: [SLUG] ntop 4.0.3 debian package for Lenny?
List-Id: Linux and Free Software Discussion <slug.slug.org.au>
X-List-Received-Date: Thu, 10 Feb 2011 23:16:58 -0000
Just wondering if anyone has a pre-built NTOP 4.0.3 for 32bit Lenny (Debian). I can build the source, but thought if I can save myself the hassle....
For the curious, I'm having some netflow v9 problems from a bunch of Cisco 3800 routers running IOS 12.4. I get the flow data and can breakdown the protocols, but not seeing HOST information in ntop that comes default with Lenny. I heard a rumour ntop 4.0.3 has some fixes for this. We're trying to isolate the end points responsible for a sustained bandwidth spike since Jan 26 on our MPLS cloud which is impacting time sensitive services (voip, citrix et al) despite QoS on the links. Optus' management tools are not very helpful as they only track aggregated bandwidth - not host/protocol stats. Hence netflow requirement from our border routers.
