"iodine lets you tunnel IPv4 data through a DNS server. This can be usable in different situations where internet access is firewalled, but DNS queries are allowed." Applies to many public hotspots...

Sounds useful, I tried to set it up using free subdomain (FreeDNS) and DNS (xname) service, with iodine running on my Asus wl500gp OpenWRT router (with dynamic IP (DynDNS)).

pmeerw.mooo.com zone on xname:

pmeerw.mooo.com.	86400	IN	SOA	ns0.xname.org. pmeerw.pmeerw.net. 2008010101 10800 3600 604800 10800
pmeerw.mooo.com.	86400	IN	NS	ns0.xname.org.
pmeerw.mooo.com.	86400	IN	NS	ns1.xname.org.
bla.pmeerw.mooo.com.	86400	IN	CNAME	pmeerw.dyndns.org.
tunnel.pmeerw.mooo.com.	86400	IN	NS	pmeerw.dyndns.org.
pmeerw.mooo.com.	86400	IN	SOA	ns0.xname.org. pmeerw.pmeerw.net. 2008010101 10800 3600 604800 10800

pmeerw.mooo.com subdomain on FreeDNS:

Type: NS
Subdomain: pmeerw
Domain: mooo.com
Address: ns0.xname.org
