ICMP is often blocked nowadays even when HTTP is allowed, so I don't think IP over ICMP is very useful.
It is possible to filter Iodine requests given that they use NULL records, which are inexistent in the real world. Some other well-known tools use TXT, which is a bit more common. TUNS (http://www.loria.fr/~lnussbau/tuns.html http://www.loria.fr/~lnussbau/tuns.html) uses CNAME and respects the DNS standard, which should have near-100% success. It's quite a bit slower though.
