I think you hit the nail on the head with that last comment. I would take it
one step further and apply this rule to ALL traffic. The way to accomplish
this is via encrypted vpn, which inherently solves numerous present day
problems with public wifi access. Basically, if hotspot providers - free,
pay or otherwise - began a norm of only allowing vpn tunnel access rather
than all raw ip traffic, I believe everyone would benefit. Here are a few of
the advantages-

-Users have a greater degree of security and privacy for their data that
doesn't rely on weak wep or other sketchy security schemes. As far as I can
tell, current shipping 802.1x solutions still don't solve the 'rogue ap'
problem. 

-Users are protected from each other on the same AP. (data xfer wise anyway,
not from direct port hacks)

-Access providers are protected from backhaul isp disconnects, lawsuits and
other ills incurred by malintentioned users. Encryption essentially creates
a double-blind user/provider relationship regarding data and acceptable use
policy. Basically, if the access provider does not have any reasonable means
of determining the content of the data being transferred, it isolates them
from direct legal responsibility. 

In this scenario, wardriving spammers, hackers, copyright violators, kiddy
porn downloaders, terrorists etc. who connect wirelessly are all beyond
possible identification by the last-mile provider. This responsibility is
kicked upstream to the vpn endpoint provider (VISP?). For instance, have any
landline telco's been subpoenaed by the RIAA for harbouring downloaders? I
can only assume current ISP's will be adopting this end-point role in an
attempt to retain ownership of their current user base...hmmm 

Also, there are several decent wireless specific vpn products out in the
market now based on SSL, TLS, etc. I have tested the Net Motion offering and
am impressed with its ability to accommodate IP address changes on the fly
without crashing applications. (Windows only unfortunately) Makes for great
inter-hotspot roaming..
