Completely untested and probably buggy as anything, but here's an 
absolutely minimal case-insensitive dictionary.

class CaselessDict(dict):
    def __setitem__(self, key, value):
        super(CaselessDict, self).__setitem__(key.lower(), value)
    def __getitem__(self, key):
        return super(CaselessDict, self).__getitem__(key.lower())
