A couple things come to mind (assuming this works on single word headers which I've been unable to get working)
1. Modifying headers such as 'Host' to access other virtualhosts on the
same ip, or breaking weak CSRF protections by modifying the 'Referer' header (http://www.securityfocus.com/archive/1/441014)
2. Potential shared virtual hosting browser cache poisoning?
3. Abusing transparent proxies via Host header modification
