So every computer on the internet will be running IPSec, doubtful, IPSec can be used from computer to computer but then everything else will be still unencrypted which pretty much defeats the point. The most import aspect of the encryption lies between the client and the AP, where sniffing is possible do to the topologies of AP's.
The standard access point is only a 133 Mhz processor. You could use it further upstream possibly, but as in for integration into the AP, it would cost a lot more per AP. AES is going to be the de facto encrpytion for wireless. Unfortunately it will take more than a firmware upgrade to the ap due to intense CPU usage.
802.1x authentication is not a new concept. It was developed many years ago for incorporation into the HP ProCurve product line for port based authentication. The good thing about 802.1x is that at least it does provide some encryption from the authenticator to the radius server. So its either this of captive portal, which is implemented into hotspot controllers to provide authentication via redirection of http requests to a website that requests user/password pairs authenticated off a radius server. Pick your tool, something needs to be done.
I believe that the speeds are somewhere around 54 Mbps area, essentially this is bring OFDM ( Orthogonal Frequency Divison Multiplexing) to lower frequencies. This being a frequency hopping. Some companies like alvarion and some others will be able to upgrade there exsisting technology via flash, not 802.11b stuff but most of the 5.8 gear outdoor stuff that is out on the market, or I could be totally wrong!

Becareful you dont want to be suspected of thoughtcrime.
