If somebody is ignorant enough to implement IP over HTTP, why should they be accommodated? There are numerous reasons why there are other port numbers to TCP than 80 and other protocol numbers to IP than 6.
Unlike some people that immediately jump to conclusions, that someone may be not arrogant, but bright - using port TCP 80 is an excellent way to bypass firewalls. If your firewall performs content analysis, one can simply encode the data in valid HTML code. Alex
